# Perimeter of a Rectangle Calculator

Every geometrical shape has some related measures that we calculate in our educational career. A rectangle is a two-dimensional shape that has multiple related measurements including perimeter, area, and others. It may be difficult to find the perimeter of a rectangle if you don’t know the formula and method to do so.

In this regard, a handy approach to finding the perimeter is using the perimeter of a rectangle calculator. It is a maths calculator that will help you in finding the perimeter using your given input values. By using this calculator, you can easily find the perimeter with any values you have for a rectangle. Keep reading to learn about this tool or manual approach to finding the perimeter of a rectangle.

## What is the Perimeter of a Rectangle?

In general definition, the perimeter is the region that comes under the boundaries of all four sides of a rectangle. We can say that it is the region that is surrounded by the sides of the given rectangle. It is pretty simple to find this measurement using a simple approach that we will discuss further in the following sections.

### Formula for the perimeter of a rectangle

As mentioned, the Perimeter is the region that comes under the four sides of a rectangle. It means that this value depends on all sides of the rectangle. That’s why the formula for finding this measure is, to sum up, the lengths of all sides.

In simple words, the Perimeter of a rectangle will be equal to the addition of all sides of a rectangle. If a rectangle has four sides, “a”, “b”, “c”, and “d”, its perimeter will be given as,

Perimeter of a rectangle = a + b + c + d


## How to find the Perimeter of a rectangle?

Finding the Parameter of a rectangle is not a difficult task if you have values of its sides. But we have solved an example here by following which you can understand it properly.

Example 1:

Find the Perimeter of a rectangle with sides having measures of 4 cm in length and 6 cm in width.

Solution:

As we know,

a = c = 4 cm

b = d = 6 cm


By using the above-mentioned formula,

Perimeter = 4 + 6 + 4 + 6 cm


So,

Perimeter = 20 cm


### How to use the perimeter of a rectangle calculator?

### FAQ | Perimeter of a Rectangle Calculator

What are the rules for perimeter?

To find the perimeter, we must have measures of all sides of a particular geometrical shape.

What is the rule for the perimeter of a rectangle?

For finding the perimeter of a rectangle, we must have at least two different lengths because a rectangle has four sides with two sides of equal measure

What are the area and perimeter of a rectangle?

The area of a rectangle is the product of the width and length of a particular figure while the perimeter is the addition of all sides of the rectangle.

The perimeter of a rectangle is 60 m. If its length is twice its breadth, then what is its area?

As per the given requirements, the length of a rectangle will be 20 m and its width will be 10 m if its perimeter is 60 m. So, the area of that triangle will be the multiplication of length and width which comes out to be 200 square meters.

The perimeter of a rectangle is 82m and its area is 400 (m square) then the breadth of the rectangle is?

Using the given conditions, the breadth/width of the rectangle with the above measurements will be 16 m.
