    Best Answer: Ab = 1.25Aa

    80 = 1.25Aa

    Aa = 64

    Aa = Sa^2

    64 = Sa^2

    Sa = 8

    Pa = 4S

    Pa = 4 (8)

    Pa = 32

    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
