A lot is 2.5 acres. How many square feet does this represent?
Correct Answer
A) 108,900 square feet
Since one acre equals 43,560 square feet, 2.5 acres = 2.5 × 43,560 = 108,900 square feet.
Why This Is the Correct Answer
Option A is correct because it properly applies the standard conversion factor of 43,560 square feet per acre. The calculation multiplies 2.5 acres by 43,560 square feet per acre, yielding 108,900 square feet. This demonstrates the correct mathematical process: 2.5 × 43,560 = 108,900. The answer represents the total square footage contained within a 2.5-acre parcel of land.
Why the Other Options Are Wrong
Option B: 10,890 square feet
This answer appears to be the result of dividing 43,560 by 4 (10,890), which might occur if someone incorrectly thought 2.5 acres was somehow a fraction of the base acre measurement rather than a multiple.
Option C: 43,560 square feet
This is the square footage of exactly one acre (43,560), suggesting the test-taker forgot to multiply by 2.5 or misread the question as asking for a single acre.
Option D: 2,500 square feet
This answer of 2,500 appears to confuse the decimal 2.5 with a direct square footage number, completely ignoring the acre-to-square-feet conversion process.
The '4-3-5-6-0' Acre Memory Method
Remember '43,560' as 'Four-Three-Five-Six-Zero' - think of it as counting '4, 3, 5, 6' then adding a zero. You can also remember 'Acres Create Square Feet: 43,560' or visualize a football field (about 1.3 acres) to anchor the concept that acres are large units.
How to use: When you see any acre conversion question, immediately write down '43,560 sq ft = 1 acre' then multiply or divide as needed. For this question, you'd write '2.5 × 43,560 = ?' and calculate step by step.
Exam Tip
Always double-check your decimal placement in these calculations - multiply carefully and verify your answer makes logical sense (2.5 acres should be more than double the square footage of 1 acre).
Common Mistakes to Avoid
- -Forgetting to multiply by the acreage amount and just stating 43,560
- -Confusing the conversion direction (dividing instead of multiplying)
- -Decimal point errors in the final calculation

Analysis
This question tests fundamental area conversion skills that are essential for real estate appraisers. Converting between acres and square feet is a basic calculation that appears frequently in property valuation, land assessment, and comparative analysis. The ability to quickly and accurately perform these conversions is critical when analyzing lot sizes, calculating price per square foot, or determining land values. Understanding these conversions helps appraisers communicate property dimensions in the most appropriate units for different contexts and stakeholders.
Background Knowledge
The fundamental conversion factor in real estate is that one acre equals exactly 43,560 square feet, which is derived from the historical definition of an acre as a furlong (660 feet) times a chain (66 feet). This conversion is used constantly in real estate appraisal, land development, and property analysis.
Real-World Application
Appraisers use this conversion when analyzing comparable sales with different lot size reporting methods, calculating land value per square foot, determining building coverage ratios, or explaining property dimensions to clients who may be more familiar with one unit than another.
