    Answer:

    W=1 4/5 feet

    L= 2 2/5 feet

    Step-by-step explanation:

    3L = 4W     L = 4W/3

    2L+2W = 8 2/5

    Substitute L

    2(4W/3)+2W = 8 2/5

    8W/3+2W = 8 2/5

    multiply both sides by 3

    8W+6W = 24 6/5

    14W = 25 1/5

    Divide both sides by 14

    14W/14 = (25 1/5)/14

    W = (126/5)/14 = 9/5 = 1 4/5

    Substitute for W

    L = 4(1 4/5)/3

    L = (4)(9/5)/3 = (36/5)/3 = 12/5 = 2 2/5
