How big is The National Mall?

Answer 1

The National Mall in Washington, D.C. is approximately 146 acres in size. It stretches for about 2 miles from the United States Capitol to the Lincoln Memorial. The Mall is flanked by various Smithsonian museums, monuments, and memorials, making it a significant cultural and historical landmark in the United States.

Answer 2

Here's an approximate answer. First, a definition. Let's take the mall to be a rectangle bounded on the East by the Capitol, on the West by the Lincoln Memorial, and on the North and South by the buildings of the Smithsonian. (It's possible to take definitions which would make it larger.) This rectangle is about 11,500 feet long (a little over two miles) and nearly 1000 feet wide. That makes it something over 250 acres. A good cartographer could give a better answer.
