    P = 2 (L + W)

    P = 150

    L = 5W + 7

    150 = 2 (5W + 7 + W)

    150 = 2 (6W + 7)

    150 = 12W + 14

    150 - 14 = 12W

    136 = 12W

    136/12 = W

    11.33 (or 11 1/3) = W < = = = width

    L = 5W + 7

    L = 5 (34/3) + 7

    L = 170/3 + 7

    L = 170/3 + 21/3

    L = 191/3 (or 63 2/3) = L < = = = length
