George has a square sandbox in the backyard. the sandbox has an area of 160 square feet. to the nearest foot, what is the length of one side of the sandbox? 13 ft 12 ft 40 ft 80 ft

We know that the sandbox is square, and that the area is 160 sq ft. Since A = s^2 for a square, let's work backwards and find s if A = 160 sq ft = s^2.

s^2 = 160 = 16(10). We do this because 16 is the largest perfect square factor of 160.

Then the length of one side of the square is approx. s = 4√10 ft (12.65 ft)
