One acre equals how many square feet?

• A. 43,560 square feet
• B. 4,356 square feet
• C. 435,600 square feet
• D. 1,000 square feet

Answer: (A)

One acre is defined as 43,560 square feet. This comes from the traditional way land is measured: an acre can be viewed as a rectangle 66 feet by 660 feet (a chain is 66 feet, and ten chains make 660 feet), and multiplying 66 by 660 gives 43,560 square feet. It’s also 4,840 square yards since a square yard is 9 square feet (4,840 × 9 = 43,560). The other numbers are off by factors of ten or more, so they don’t represent an acre.
