Ontario Ranch covers how many square miles?

• A. 12 square miles
• B. 14 square miles
• C. 13 square miles
• D. 15 square miles

Answer: (C)

Think in terms of unit conversion. Area can be expressed in different units, so to compare acres to square miles you use the fact that 1 square mile equals 640 acres. To see which option fits, multiply the square miles by 640 to get acres, or divide acres by 640 to get square miles. If Ontario Ranch covers about 8,320 acres, dividing by 640 gives 13 square miles (8,320 ÷ 640 = 13). The other options correspond to 7,680, 8,960, and 9,600 acres, which don’t match the commonly cited size as well. So 13 square miles is the best match.
