Question

Jo is on the phone with a gardener who asks about the square feet of Jo's backyard. Jo counts 20 steps long and 40 steps wide (with each step being about 3 feet). About how many square feet is the backyard?
a. 120 ft2

b.360 ft2

c. 800 ft2

d. 7,200 ft2

Answer 1

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.
