For instance, 20 miles square (20 × 20 miles) has an area equal to 400 square miles; a rectangle of 10 × 40 miles likewise has an area of 400 square miles, but it is not 20 miles square. One square mile is equal to: 4,014,489,600 square inches. 27,878,400 square feet.
Also, how many areas are in a square mile? So a 1-mile side is 5280 feet and there are 25.3 acres per mile, so each acre defined as a square is 208.7 feet per side (5280/25.3 = 208.7). Each “square” acre is 43,560 ft^2 (208.7^2), and there are 640 of them in a square mile, so a square mile contains 43,560 • 640 = 27,878,400 square feet (which is also 5280^2).
Secondly, how many football fields can fit in a square mile?
