Question

According to the USDA, a small family farm has an average area of 231 acres.

a. What is this area in square miles? Use this fact that 1 square mile is 640 acres.
b. What is this area in square feet? Recall: 1 mile = 5,280 ft.

Answer 1

Therefore, the area of a small family farm in square feet is 9,923,640.

Explanation:

a. To convert acres to square miles, we divide the number of acres by 640:

231 acres / 640 acres/square mile = 0.36 square miles

Therefore, the area of a small family farm in square miles is 0.36.

b. To convert acres to square feet, we first need to convert acres to square yards (since there are 9 square feet in a square yard):

231 acres x 4840 square yards/acre x 9 square feet/square yard = 9,923,640 square feet

Therefore, the area of a small family farm in square feet is 9,923,640.
