Rectangle Perimeter Calculator

Introduction

Welcome to our Rectangle Perimeter Calculator! which will help you calculate the rectangle’s perimeter quickly and easily. A Rectangle is a two-dimensional closed figure with four sides, where opposite sides are equal and parallel. Also, the internal angles of the rectangle all measure 90 degrees.

The perimeter of the rectangle is the total distance around the shape. Hence, we can get the perimeter by adding the length of the sides. Generally, we measure it in units like centimeters, inches, meters, feet, etc.

How to use the Rectangle Perimeter Calculator?

Using the Rectangle Perimeter calculator, you can calculate the perimeter of the rectangle by inputting the values for the length and breadth of the rectangle.

The variables in the Rectangle Perimeter Calculator include

Length (l)
The length of the rectangle.

Breadth (B)
The Breadth of the rectangle.

Perimeter (P)
The sum of lengths of the four sides of the rectangle.

What is a Rectangle?

A rectangle is a closed four-sided Polygon where the opposite sides are equal and parallel. The rectangle also has four angles, which measure 90 degrees each.

Some of the properties of a rectangle include

  1. Opposite sides of a rectangle are equal and parallel to each other.

  2. Each interior angle of a rectangle measures 90 degrees.

  3. The sum of all interior angles of a rectangle is 360 degrees.

  4. The length of a rectangle’s diagonals are equal and bisect each other.

How is the Perimeter of the Rectangle Calculated?

Perimeter is the distance around the shape; for a rectangle, to calculate the perimeter, so we have to add the lengths of each of the sides of the rectangle.

We can calculate the perimeter of the rectangle by using the following formula.

P=2×(l+b)P = 2 \times ( l + b)

Where,

l = Length of the rectangle

b = Breadth of the rectangle

Examples

Given a rectangle of length 5 cm and breadth 3 cm. What is the perimeter of the rectangle?

We can calculate the perimeter of the rectangle by using the following formula.

P=2×(l+b)=2×(5+3)=16  cm\begin{aligned} P &= 2 \times (l + b) \\[10pt] &= 2 \times (5 + 3) \\[10pt] &= 16 \; cm \end{aligned}

As shown above, in the calculation, the perimeter of the rectangle is 16 cm.
