    The perimeter of the square is 36cm.

    Step-by-step explanation:

    The area is found when you multiply the length x width. 9 x 9 = 81. Since a square has equal sides. 9cm would be on the 4 sides. 9 x 4 = 36cm

    36 cm

    Step-by-step explanation:

    The area of a square is given by

    A = s^2

    81 = s^2

    Take the square root of each side

    9 = s

    We want the perimeter

    P = 4s

    P = 4*9

    P = 36
