How to Calculate Area: Step-by-Step Guide
Whether you are measuring square footage for flooring, buying paint, or completing geometry homework, calculating area is simple once you know the shape's dimensions.
Step 1: Measure Dimensions
Use a measuring tape to find the dimensions of your room or object in feet, meters, or inches.
Step 2: Apply the Shape's Formula
- Square / Rectangle Room: Length × Width. (e.g., a 12 ft × 15 ft room = 180 sq ft).
- Circular Garden: π × radius². (e.g., radius 5 m → 3.14159 × 25 = 78.54 sq m).
- Triangular Lot: ½ × Base × Height.
