1. 15^2 is 15*15 = 225
2. area of square = L*W and if that is total to 36, it would be 6 because if the L was 6 and the W was 6, the area would be 36
3. 256 divided by 4 is 64ft because if it’s square, all sides are equal. and perimeter is side+side+side+side and if those are equal to 256, your answer is 64
