Question: What is the total area of the capitol of Russel Farnham's birth state?

full_context: Document 1: South Bay, Boston: South Bay is a 10-acre (40,000 m²) site in Boston, Massachusetts between Chinatown and the Leather District. It is roughly bounded by Kneeland Street, Hudson Street, the Massachusetts Turnpike mainline, and the Interstate 93 mainline. Currently owned by the Massachusetts Turnpike Authority (MTA), the area is taken up by a major highway interchange between 90, 93, and local streets. There were originally plans to re-develop the area with a 600-foot tall office tower, but no such project has taken place.
Document 2: Boston: In addition to city government, numerous commissions and state authorities—including the Massachusetts Department of Conservation and Recreation, the Boston Public Health Commission, the Massachusetts Water Resources Authority (MWRA), and the Massachusetts Port Authority (Massport)—play a role in the life of Bostonians. As the capital of Massachusetts, Boston plays a major role in state politics.
Document 3: Jonathan Russell: Born in Providence, Rhode Island on February 27, 1771, Russell graduated from Brown University (then Rhode Island College) in 1791. He studied law and was admitted to the bar, but did not practice. He engaged in mercantile pursuits for a number of years. In 1808 he was appointed Collector of the Port of Bristol.
Document 4: Boston: Tourism also composes a large part of Boston's economy, with 21.2 million domestic and international visitors spending $8.3 billion in 2011; excluding visitors from Canada and Mexico, over 1.4 million international tourists visited Boston in 2014, with those from China and the United Kingdom leading the list. Boston's status as a state capital as well as the regional home of federal agencies has rendered law and government to be another major component of the city's economy. The city is a major seaport along the United States' East Coast and the oldest continuously operated industrial and fishing port in the Western Hemisphere.
Document 5: Boston: Boston has an area of 89.6 square miles (232.1 km2)—48.4 square miles (125.4 km2) (54.0%) of land and 41.2 square miles (106.7 km2) (46.0%) of water. The city's official elevation, as measured at Logan International Airport, is 19 ft (5.8 m) above sea level. The highest point in Boston is Bellevue Hill at 330 feet (100 m) above sea level, and the lowest point is at sea level. Situated onshore of the Atlantic Ocean, Boston is the only state capital in the contiguous United States with an oceanic coastline.
Document 6: Boston: Federally, Boston is split between two congressional districts. The northern three-fourths of the city is in the 7th district, represented by Mike Capuano since 1998. The southern fourth is in the 8th district, represented by Stephen Lynch. Both are Democrats; a Republican has not represented a significant portion of Boston in over a century. The state's senior member of the United States Senate is Democrat Elizabeth Warren, first elected in 2012. The state's junior member of the United States Senate is Democrat Ed Markey, who was elected in 2013 to succeed John Kerry after Kerry's appointment and confirmation as the United States Secretary of State.
Document 7: Houston: According to the United States Census Bureau, the city has a total area of 656.3 square miles (1,700 km2); this comprises 634.0 square miles (1,642 km2) of land and 22.3 square miles (58 km2) of water. The Piney Woods is north of Houston. Most of Houston is located on the gulf coastal plain, and its vegetation is classified as temperate grassland and forest. Much of the city was built on forested land, marshes, swamp, or prairie which resembles the Deep South, and are all still visible in surrounding areas. Flatness of the local terrain, when combined with urban sprawl, has made flooding a recurring problem for the city. Downtown stands about 50 feet (15 m) above sea level, and the highest point in far northwest Houston is about 125 feet (38 m) in elevation. The city once relied on groundwater for its needs, but land subsidence forced the city to turn to ground-level water sources such as Lake Houston, Lake Conroe and Lake Livingston. The city owns surface water rights for 1.20 billion gallons of water a day in addition to 150 million gallons a day worth of groundwater.
Document 8: South Pass (Wyoming): In 1823 a St. Louis merchant named William Henry Ashley (started the rendezvous system) led a party up the Sweetwater to its source, rediscovered the pass (look back to previous paragraph), and spent the summer in its vicinity trapping. He returned again in 1824, this time going as far as Great Salt Lake and setting up a trading post there, which after three profitable years he sold to the Rocky Mountain Fur Company, headed by William Sublette, and David Jackson.
Document 9: Russel Farnham: Russel Farnham was born in Massachusetts in 1784 and left home to join one of two expeditions organized by John Jacob Astor to establish the Pacific Fur Company at the mouth of the Columbia River. Farnham, hired as a clerk, was part of the "Tonquin" party under Captain Jonathan Thorn who were to travel by sea around Cape Horn arriving on the Pacific coast. However, the party soon met with disaster with the death of Thorn and the destruction of their ship soon after their arrival.
Document 10: Fort Clatsop: Fort Clatsop was the encampment of the Lewis and Clark Expedition in the Oregon Country near the mouth of the Columbia River during the winter of 1805 - 1806. Located along the Lewis and Clark River at the north end of the Clatsop Plains approximately 5 miles (8.0 km) southwest of Astoria, the fort was the last encampment of the Corps of Discovery, before embarking on their return trip east to St. Louis.
Document 11: Fort William (Oregon): Fort William was a fur trading outpost built in 1834 by the American Nathaniel Jarvis Wyeth, a Boston merchant, backed by American investors. It was located on the Columbia River on Wappatoo Island near the future Portland, Oregon. After a few years, in 1837 Wyeth sold the post to the British Hudson’s Bay Company, which had much more power in the region from its base at Fort Vancouver on the north side of the Columbia River near Fort William.
Document 12: Boston: Boston is surrounded by the "Greater Boston" region and is contiguously bordered by the cities and towns of Winthrop, Revere, Chelsea, Everett, Somerville, Cambridge, Newton, Brookline, Needham, Dedham, Canton, Milton, and Quincy. The Charles River separates Boston from Watertown and the majority of Cambridge, and the mass of Boston from its own Charlestown neighborhood. To the east lie Boston Harbor and the Boston Harbor Islands National Recreation Area (which includes part of the city's territory, specifically Calf Island, Gallops Island, Great Brewster Island, Green Island, Little Brewster Island, Little Calf Island, Long Island, Lovells Island, Middle Brewster Island, Nixes Mate, Outer Brewster Island, Rainsford Island, Shag Rocks, Spectacle Island, The Graves, and Thompson Island). The Neponset River forms the boundary between Boston's southern neighborhoods and the city of Quincy and the town of Milton. The Mystic River separates Charlestown from Chelsea and Everett, and Chelsea Creek and Boston Harbor separate East Boston from Boston proper.

Document 15: Boston: With nearly a third of Bostonians using public transit for their commute to work, Boston has the fifth-highest rate of public transit usage in the country. Boston's subway system, the Massachusetts Bay Transportation Authority (MBTA—known as the "T") operates the oldest underground rapid transit system in the Americas, and is the fourth-busiest rapid transit system in the country, with 65.5 miles (105 km) of track on four lines. The MBTA also operates busy bus and commuter rail networks, and water shuttles.
