    Answer:

    W = 6

    L = 36

    Step-by-step explanation:

    2L + 2W = 84

    L = 6W

    Substitute for L in the first equation

    2 (6W) + 2W = 84

    12W + 2W = 84

    14W = 84

    W = 6

    Substitute W in the first equation

    2L + 2(6) = 84

    2L + 12 = 84

    2L = 72

    L = 36

    Plug both values in both equations to be sure

    2(36) + 2(6) = 84

    36 = 6 * 6

    Hope that helps!
