    Step-by-step explanation:

    p = 106

    L = 8 + 4W

    p = 2L + 2W

    p = 2 (8 + 4W) + 2W

    p = 16 + 8W + 2 W

    p = 16 + 10W

    106 = 16 + 10W

    106 - 16 = 10W

    90 = 10W

    90/10 = W

    9 = W

    W = 9

    L = 8 + 4W

    L = 8 + 4 (9)

    L = 8 + 36

    L = 44

    44 + 44 + 9 + 9 = 106

    44 * 9 = Area = 396
