    Answer:

    The area is 15 feet

    Step-by-step explanation:

    So you are going to need two different equations-

    l = w(3)

    2l + 2w = 40

    Insert the first equation into the second-

    2(3w) + 2w = 40

    Simplify this equation-

    6w + 2w = 40

    8w = 40

    Divide both sides by 5

    w = 5

    Solve first equation

    l = 5(3)

    l = 15

    Then find the area-

    5 x 15 = 75
