Area Calculation (Square Footage)

Definition

Area calculation involves determining the square footage or acreage of a property using geometric formulas. Key conversions: 1 acre = 43,560 square feet, 1 mile = 5,280 feet, 1 section = 640 acres.

Example

A rectangular lot measures 150 feet by 200 feet. Area = 150 x 200 = 30,000 square feet. To convert to acres: 30,000 / 43,560 = 0.689 acres. If land sells for $5/sq ft, lot value = 30,000 x $5 = $150,000.

Exam Tip

Memorize that 1 acre = 43,560 square feet and 1 section = 640 acres. For irregular lots, practice breaking them into rectangles and triangles. Always double-check your units—don't mix feet and inches or square feet and acres in the same calculation.
