About Perimeter

The perimeter of a shape is the total length of its boundary or the distance around its edges. It is a fundamental geometric measurement used in various applications.

Common Perimeter Formulas
  • Rectangle: P = 2L + 2W (where L is length and W is width)
  • Square: P = 4s (where s is the side length)
  • Circle: P = 2πr or P = πd (where r is radius and d is diameter)
  • Triangle: P = a + b + c (where a, b, and c are the side lengths)
  • Equilateral Triangle: P = 3s (where s is the side length)
  • Regular Polygon: P = n × s (where n is the number of sides and s is the side length)
Applications
  • Construction: Calculating fencing, borders, framing materials
  • Landscaping: Measuring garden borders, walkways, edging
  • Architecture: Planning room dimensions, floor plans
  • Manufacturing: Determining material needs for frames and edges
  • Agriculture: Measuring field boundaries, irrigation planning
