Perimeter Of A Rectangle

Introduction

The perimeter of a rectangle can be described as the distance around all four sides of the rectangle. The green box around the rectangle below indicates the perimeter of the rectangle.

Terms

Rectangle - A polygon with four straight sides and four right angles, esp one with unequal adjacent sides.
Perimeter - The distance around all the edges of a geometric figure.

Lesson

Calculating the perimeter of a rectangle is as easy as simply adding the lengths of all the sides together. The formula for this calculation is:

Perimeter of a Rectangle Formula

Perimeter = 2*b + 2*h

where ‘b’ is the base length, and ‘h’ is the height

So for a rectangle with a base of 5 and a height of 2, the perimeter would be:

Examples

Perimeter of a Rectangle (Example #1)

Find the perimeter
Perimeter = 2 * Length + 2 * Width
Perimeter = 2 * + 2 *

Perimeter of a Rectangle (Example #2)

Find the perimeter
Perimeter = 2 * Length + 2 * Width
Perimeter = 2 * + 2 *

Perimeter of a Rectangle (Example #3)

Find the perimeter
Perimeter = 2 * Length + 2 * Width
Perimeter = 2 * + 2 *

Perimeter of a Rectangle (Example #4)

Find the perimeter
Perimeter = 2 * Length + 2 * Width
Perimeter = 2 * + 2 *
