    Answer: The length is 24.5 feet.

    Step-by-step explanation:

    The formula for the perimeter of a rectangle is P = 2L + 2W.

    Plug in the values you know

    87 = 2L + 2 (19)

    Solve for L

    87 = 2L + 38

    subtract 38 from both sides

    49 = 2L

    divide both sides by 2

    L = 24.5
