What is the total number of acres in a township that covers 36 square miles?

• A. 14,400
• B. 23,040
• C. 11,520
• D. 32,000

Answer: (B)

The main idea is converting square miles to acres. A township is 36 square miles in area, and 1 square mile equals 640 acres. Multiply 36 by 640: 640 × 36 = 19,200 + 3,840 = 23,040. So the total acres are 23,040. The other numbers don’t fit a 36 square mile area because they result from different total square miles.
