Answer:

The answer is option d which is 7200ft^2.

Step-by-step explanation:

As Jo counts 20 steps long with 1 step=3 feet so;

length = 20*3=60 feet

also 40 steps wide with 1 step = 3 feet so;

width = 40*3=120 feet

thus the area will be

Area = length * width = 60*120=7200ft^2

Area =7200ft^2

thus the backyard is 7200 square feet.
