1 foot = 0.3048 meter 400 sq feet = 400 x 0.3048 x 0.3048 sq meters
I will lead you in finding this answer. The first thing you would do is use the formula A = s^2 backwards. In other words, you will plug in the 10000 as your area and go backwards to find your answer. The best way to do this is to find the square root of 10000. Then, after you find your answer, multiply it by 4 to find the perimeter, which is 400. Hope this helps for future reference!8th grader
one square foot is equal to 0.0929 square meters, multiply this by 400 and the answer is 37.16 square meters
400 sq metres = 4305.564 sq feet (to 3 dp)
