I want to know the answer to the following question:
How much land did the Allen brothers buy?
All the background I'm provided with is that "In August 1836, two real estate entrepreneurs—Augustus Chapman Allen and John Kirby Allen—from New York, purchased 6,642 acres (26.88 km2) of land along Buffalo Bayou with the intent of founding a city.". Is that enough to answer the question?
Answer: yes
