You need to estimate the square root of 200 ft². Rewrite 200 as 2 x 100, then square root of (2*100) is:
10 sqrt(2). The sqrt(2) = 1.414, so the length of each side of the square will be 10 1.414 = 14.14 ft or about 14 ft.
200 = 10 2 ≈ 14
The approximate length of each side of the square field is 14 feet. This was calculated by taking the square root of the area, 200 square feet, which is about 14.14 feet when calculated. Rounding to the nearest foot gives us the final answer of 14 feet.
