Which option equals 2 acres in square feet?

• A. 40,000 ft^2
• B. 87,120 ft^2
• C. 130,680 ft^2
• D. 174,240 ft^2

Answer: (B)

Converting acres to square feet uses the fact that one acre equals 43,560 square feet. So two acres is 2 × 43,560 = 87,120 square feet. The number 87,120 ft^2 matches 2 acres. The other values correspond to different acreages: 40,000 ft^2 is less than an acre, 130,680 ft^2 is 3 acres, and 174,240 ft^2 is 4 acres.
