Answer:

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
