    The perimeter of the envelop is 30 in.

    Step-by-step explanation:

    Given,

    The length (l) of the envelop = 7 inches

    Width (b) of the envelop = 8 inches

    To find the perimeter of the envelop.

    Formula

    The perimeter of a rectangle = 2 (l+b)

    So,

    The perimeter of the envelop = 2 (7+8) in

    = 30 in
