John’s family bought acres of land. How many square feet is that?

a. 40,250 square feet
b. 53,370 square feet
c. 65,340 square feet
d. 71,120 square feet

Answer: c

Explanation:
We know that 1 acre = 43,560 square feet. In order to find how many square feet is in
acres, we have to multiply those numbers as follows:
1½ acres x [43,560 square feet / 1 acre] = 65,340 square feet.
Note that the units for acres disappear and we are left with only square feet.
