📏 How to Find Perimeter: Your Complete Guide

How to find perimeter is a common question when dealing with geometric shapes. Whether you’re studying geometry or working on a real-world project, calculating the perimeter is an essential skill. The perimeter is simply the total distance around a two-dimensional shape.

📐 What Is Perimeter?

The perimeter of a shape is the total length of all its sides. It is essentially the outer boundary or the “fence” around the shape. It’s an important measurement used in many areas like construction, art, sports, and more.

🧮 Formula to Find Perimeter

The method to find the perimeter depends on the type of shape you are working with. Here are some common formulas:

1. Rectangle or Square:
   • Perimeter = 2 × (Length + Width)
   • For a square, since all sides are equal: Perimeter = 4 × Side
2. Triangle:
   • Perimeter = Side1 + Side2 + Side3
   • Simply add the lengths of all three sides.
3. Circle:
   • For a circle, the perimeter is called the circumference.
   • Circumference = 2 × π × Radius
4. Other Polygons (like Pentagon, Hexagon, etc.):
   • Perimeter = Number of sides × Length of one side

1. Rectangle

Suppose you have a rectangle with a length of 8 cm and a width of 5 cm:

• Perimeter = 2 × (8 + 5) = 2 × 13 = 26 cm

2. Square

For a square with each side measuring 4 cm:

• Perimeter = 4 × 4 = 16 cm

3. Triangle

If a triangle has sides of lengths 6 cm, 8 cm, and 10 cm:

• Perimeter = 6 + 8 + 10 = 24 cm

4. Circle

For a circle with a radius of 7 cm:

• Perimeter (Circumference) = 2 × π × 7 ≈ 2 × 3.14159 × 7 ≈ 43.98 cm
