    Formula for are of a rectangle:

    A = L * W

    1st isolate W

    147 = 3W * W

    147 = 3W^2

    divide 147 by the by 3 on bot sides

    29 = W^2

    get ride of the square by square rooting on both sides

    7 = W

    2nd find the perimeter

    P = 2 (7) + 2 (21)

    P = 14 + 42

    P = 56
