Perimeter is the total distance around the outside of a two-dimensional shape. It's the sum of all the sides of a polygon or the circumference of a circle.
Common Formulas:
- • Rectangle: P = 2(length + width)
- • Square: P = 4 × side
- • Circle: C = 2πr (circumference)
- • Triangle: P = side₁ + side₂ + side₃
- • Regular Polygon: P = n × side length
Applications:
- • Fencing and boundary calculations
- • Construction and architecture
- • Material estimation (trim, edging)
- • Sports field design
- • Garden and landscape planning
