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

What is the Perimeter Calculator?

The Perimeter Calculator is a handy tool that helps you find the perimeter of various shapes. Whether you're working with a rectangle, circle, or triangle, this calculator simplifies the process. It allows you to enter the necessary measurements and gives you the total distance around the shape's edge. This tool is perfect for students, teachers, and anyone who needs quick calculations.

Shapes You Can Calculate

This calculator can handle a wide range of shapes, each with its own formula for calculating perimeter. Here are some shapes you can choose from:

  • Rectangle
  • Square
  • Circle
  • Triangle
  • Parallelogram
  • Pentagon
  • Hexagon
  • Ellipse

Each shape has unique inputs, which the calculator processes to give accurate results.

Understanding Perimeter

Perimeter is the total length of the boundaries of a shape. It tells you how far you would travel if you walked around the edge. For example, if you have a rectangle, the perimeter is found by adding together all four sides. Knowing how to calculate perimeter is helpful in many real-life situations, such as crafting, landscaping, and construction.

Input and Output Details

When using the Perimeter Calculator, you will need to enter specific measurements based on your chosen shape. The calculator will then provide you with the perimeter in your preferred units, such as meters, centimeters, or inches. You can also opt to see the formula used and the steps taken to arrive at the answer, which is great for learning.

Why It's Useful for Students
