koban [17]

Answer:

33.33 square yards

Step-by-step explanation:

(20 ft)(15 ft) = 300 ft^2

Converting this to square yards, we multiply the above result by

(1 yd)^2

------------

(3 ft)^2

obtaining

(300 ft^2)     (1 yd)^2

-------------- * ------------- = 33.33 square yards

        1            9 ft^ 2
