one square foot is equal to 0.0929 square meters, multiply this by 400 and the answer is 37.16 square meters
1 acre = 43,560 square feet400 ft x 400 ft = 160,000 square feet = (160,000 / 43,560) = 3.673 acres (rounded)
It would be a 20 by 20 ft square
12" x 12" = 1 square foot. 400 of them are required in order to cover 400 square feet.
About 400 if everybody was squished

A 40-foot by 10-foot yard contains 400 square feet.
If that is 20ft by 20ft then there are 400 square feet

It is 80 you stupid===============================Another contributor observed:The first answer to this question comes from a contributor who is not onlyoffensive in his attitude, but wrong in his math as well.The question doesn't say "5 square foot pieces". It says "5 foot square pieces".From that terminology, we understand that each piece is a square, with 5-foot sidesand an area of 25 square feet.It takes (400/25) = 16 of these pieces to cover an area of 400 square feet.
No one answer, since it depends on the shape of the 400 square foot figure. If it is a square 20x20, then the diagonal is about 28.25 ft.

A tile measuring 2 foot by two foot (which, incidentally, is an unusually large tile) has an area of 4 square feet, so it would take 100 such tiles to cover a 400 square foot floor.
