    A square has equal sides. To find the area, you multiply the length and the height.

    x*x=121

    x^2=121

    x=11

    The length of each side is 11

    A square has equal sides. To find the perimeter, you add all the sides together.

    x+x+x+x=28

    4x=28

    x=7

    The length of each side is 7
