    9 cm^2

    Step-by-step explanation:

    If the perimeter of the square is 12 cm, then the length of ONE side is (1/4) of that, or 3 cm.

    The area of this square is A = s^2, where s is the length of one side.

    Here we have A = (3 cm) ^2 = 9 cm^2.

    its 9

    Step-by-step explanation:

    a square has 4 sides

    divide perimeter by 4 and get the perimeter of one side

    then square the side or multiply the number by itself to get area

    in this case 12/4=3

    3*3=9
