    lenght = 13 inches

    width = 7 inches

    Step-by-step explanation:

    p = 2 (l+b)

    let lenght be x

    width be y

    so x=y+6

    40 = 2 (y+6 + y)

    40 = 2 (2y+6)

    20 = 2y + 6

    2y = 20-6

    2y=14

    y=7

    x=7+6=13

    so lenght is 13 inches

    width is 7 inches
