Perimeter Calculator

A Perimeter Calculator is a tool used to calculate the total length of the sides of any geometric figure, such as squares, rectangles, or circles. It is especially useful in construction, landscaping, and other design-related tasks where knowing the perimeter is essential.

Perimeter Calculator what does it do?

A Perimeter Calculator is used to quickly and accurately calculate the perimeter of a shape.

Perimeter Calculator formula

The formulas used for perimeter calculation vary based on the type of shape. For example:

1. For a Rectangle or Square:

Perimeter = 2 × (Length + Width)

1. For a Circle:

Perimeter = 2 × π × Radius

These formulas are used to accurately calculate the perimeter of the shape. For rectangles and squares, you add the length and width together and multiply by two, while for a circle, you multiply the radius by pi.

Perimeter Calculator example

Example 1: Calculating the Perimeter of a Rectangle
A rectangle has a length of 8 meters and a width of 5 meters. To calculate the perimeter:

Step 1: Determine the length and width of the rectangle.

• Length = 8 meters
• Width = 5 meters

Step 2: Apply the formula to calculate the perimeter.

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

Result: The perimeter of the rectangle is 26 meters.

Example 2: Calculating the Perimeter of a Circle
A circle has a radius of 7 meters. To calculate the perimeter:

Step 1: Determine the radius of the circle.

• Radius = 7 meters

Step 2: Apply the formula to calculate the perimeter.

• Perimeter = 2 × π × 7 meters = 2 × 3.1416 × 7 meters ≈ 43.98 meters

Result: The perimeter of the circle is approximately 43.98 meters.

The Perimeter Calculator allows you to quickly and accurately calculate the perimeter of any geometric shape.
