# 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.
