The area of square B is 25% greater than the area of square A. If the area of square B is 80 square inches, then what is the length in inches of the perimeter of square A?
area Square B = area Square A * 1.25 80 / 1.25 = area Square A area Square A = 64 area of a square = side^2 side of a square = sq root(area) side of square A = 8 So each side of square A = 8
perimeter of a square = 4 * side perimeter of square A = 32
