    The answer is 15! Heres the shown work! let x be a width

    1 1/4x be the length (or it can be 5/4 i prefer this one)

    formula for rectangle

    lxw=a

    5x/4 (x) = 180

    4[5x^2/4=180]4

    5x^2=720

    x^2=144

    x=12

    so width is 12 and length is

    5x/4

    5 (12) / 4

    60/4

    =15
