    l=15 inches

    w=9 inches

    Step-by-step explanation:

    Area=135=l*w

    l*w=135 (equation 1)

    l/w=5/3

    l=5w/3

    putting l=5w/3 in equation 1

    (5w/3) * w=135

    5w^2/3=135

    5w^2=135*3

    w^2 = (135*3) / 5

    w^2=81

    Taking square root on both sides

    w=9 inches

    l*w=135

    l=135/w

    l=135/9

    l=15 Inches
