Perimeter Calculation Applications

Fencing & Borders
Calculate fencing materials for gardens, yards, and properties. Determine border lengths for landscaping projects and property boundaries.
Construction & Building
Calculate frame perimeters for foundations, wall lengths for siding, trim calculations, and molding requirements for interior finishing.
Landscaping & Design
Plan walkway lengths, garden bed borders, patio edging, and decorative trim for outdoor design projects and landscape architecture.

Common Perimeter Examples

Rectangular Yard
50ft × 30ft yard needs 160ft of fencing: 2 × (50 + 30) = 160 feet total perimeter for complete enclosure.
Circular Garden
10ft radius garden needs 62.83ft of border: 2 × π × 10 = 62.83 feet of edging material around the circumference.
Professional Tips
Always add 5-10% extra material for waste and cuts. For irregular shapes, break them into standard shapes and sum the perimeters.
