George has a square sandbox in back yard. the sandbox has an area of 160 square feet. to the nearest foot, what is the length of one side of the sandbox?

Ok, so the sandbox is a square, so that means four sides. Now, We had to multiply to get the area, 160. So, do the opposide, and divide.

160 / 4 = 40  now to check, just do 40 x 4 = 160  it is correct

So the answer is 40. :)
