    Perimeter of a rectangle = 2 (l + w)

    l = length.

    w = width

    In this problem,

    Perimeter = 40

    w = 6

    l = ?

    Plug our numbers in.

    40 = 2 (l + 6).

    Divide each side by 2.

    20 = l + 6.

    Subtract 6 from both sides.

    14 = l

    The length is 14 inches
