    The width is 5 inches

    Step-by-step explanation:

    In order to find the width, start by labeling the width as x. Since we know the length is 8 inches longer, we can express the length as x + 8. Now we can plug these two into the perimeter formula and solve for x to get the width.

    2l + 2w = P

    2 (x + 8) + 2x = P

    2x + 16 + 2x = P

    4x + 16 = P

    4x + 16 = 36

    4x = 20

    x = 5
