    Answer:

    Down below

    Step-by-step explanation:

    P = 2L + 2W

    P = 108

    L = 2W+12

    108 = 2(2W+12) + 2W

    108 = 4W + 24 + 2W

    108 = 6W + 24

    84 = 6W

    14 = W

    W = 14

    If the width is 14, then the length is twice that plus 12, or 38

    38 + 38 + 14 + 14 = 108
