    Step-by-step explanation:

    so let's say x is the length. Then the width will be 3x-4. You add them together and multiply by two. The perimeter is 72 so the equation equala 72.

    Equation:

    (x+3x-4) * 2=72

    (4x-4) * 2=72

    8x-8=72

    8x=80

    x=10

    length:10

    width:26
