Rectangle visualization
Calculating land area is essential for property transactions, construction planning, and agricultural purposes. Follow these steps:
Use a measuring tape or professional surveying equipment to measure the length and width of your property. For irregular shapes, divide the land into regular shapes (rectangles, triangles) and calculate each separately.

Different shapes require different calculation methods:
| Shape | Formula | Example |
|---|---|---|
| Rectangle | Length × Width | 100 ft × 50 ft = 5,000 sq ft |
| Triangle | (Base × Height) ÷ 2 | (100 ft × 50 ft) ÷ 2 = 2,500 sq ft |
| Circle | π × Radius² (π ≈ 3.1416) | 3.1416 × 50 ft × 50 ft ≈ 7,854 sq ft |
