I want to know the answer to the following question:
How large is the Gateway National recreation Area in hectares?
All the background I'm provided with is that "Gateway National Recreation Area contains over 26,000 acres (10,521.83 ha) in total, most of it surrounded by New York City, including the Jamaica Bay Wildlife Refuge in Brooklyn and Queens, over 9,000 acres (36 km2) of salt marsh, islands, and water, including most of Jamaica Bay.". Is that enough to answer the question?
Answer: yes
