**Perimeter of a Figure:** Perimeter is the distance around the 2 Dimensional figure. The total length of the boundary of a plane is called the perimeter of a figure. We can find the perimeter of a closed figure by adding the length of unit squares along each of the figures. The perimeter of different shapes can be equal in measure depending on the dimensions.

Students can know how to find the perimeter of two-dimensional figures like rectangle, square, triangle, parallelogram, and so on from here. This article helps you to know the formulas to find the perimeter of the figures. Let us see some examples of the perimeter of a figure and apply them to real-time problems.

## How to Estimate the Perimeter of a Figure?

To determine the perimeter of a shape we have to add the lengths of the closed figure. Follow the steps to find the perimeter of the 2D figures from the below section.

**Step 1:** First determine the length of each side.

**Step 2:** Add the length of all the sides together to determine the distance around the shape.

**Step 3:** Deal with the variables.

**Step 4:** Pay attention to units of measurement.

### Perimeter Formulas for Different Figures

**Perimeter of a Square:**

In a square, all sides will be equal. So, to find the perimeter of a square shape we have to add all the sides. The perimeter is denoted by ‘P’

The perimeter of a square = 4 Ã— s

**Perimeter of a Rectangle:**

A Rectangle is a two-dimensional figure with the same length and breadth. Opposite sides are equal in a rectangle. It is denoted by ‘P’.

Perimeter of a rectangle = 2(L + W)

L, W are the length and width of the rectangle

**Perimeter of a Triangle:**

A triangle has three sides. The perimeter of a triangle is the sum of all three sides.

P = a + b + c

**Perimeter of a Quadrilateral:**

A quadrilateral is a polygon with four sides.

The perimeter of a quadrilateral is a + b + c + d

a, b, c, d are the length of sides

### Finding Perimeter of Different Figures Examples

We have provided a step by step explanation for all the questions for your better understanding here. Thus, we suggest the students go through the below examples to know how to find the perimeter of the figure.

**Example 1.**

Find the perimeter of the figure below.

**Solution:Â **

The above figure is a rectangle.

The length of a rectangle is 13 units.

The breadth of a rectangle is 6 units.

We know that,

Perimeter of the rectangle = Length + length + breadth + breadth

P = 13 units + 13 units + 6 units + 6 units

P = 2(13 + 6)

P = 2(19 units)

P = 38 units

Thus the perimeter of the given figure is 38 units.

**Example 2.**

Find the perimeter of the figure below.

**Solution:Â **

Given,

The side of a square is 12 cm

We know that,

The perimeter of a square = 4 Ã— s

P = 4 Ã— 12cm

P = 48 cm

Therefore the perimeter of the square is 48 cm.

**Example 3.**

Find the perimeter of the figure below.

**Solution:Â **

The above figure is an equilateral triangle.

Given,

a = 5 cm

b = 5 cm

c = 5 cm

Perimeter of Triangle = 5 + 5 + 5

P = 15 cm

Therefore the perimeter of the triangle is 15 cm.

**Example 4.**

Find the perimeter of the figure below.

**Solution:Â **

Given,

The above figure is a quadrilateral.

a = 4 inch

b = 7 inch

c = 8 inch

d = 11 inch

Perimeter of a quadrilateral is a + b + c + d

P = 4 in. + 7 in. + 8 in. + 11 in.

P = 30 in.

Therefore the perimeter of the quadrilateral is 30 inches.

**Example 5.**

Find the perimeter of the figure below.

**Solution:Â **

Given,

The above figure is a parallelogram.

a = 7 cm

b = 5 cm

c = 7 cm

d = 5 cm

Perimeter of a parallelogram is a + b + c + d

P = 7 + 5 + 7 + 5

P = 24 cm

Therefore the perimeter of a parallelogram is 24 cm.

### FAQs on Perimeter of a Figure

**1. How do you find the perimeter of a figure?**

We can find the perimeter of the figure by adding all the sides of the 2D figures.

**2. Where do we use perimeter in real life?**

Perimeter in real life helps you to find the total length of the boundary of the field or the length of the crochet or ribbon required to cover the border of a table mat etc.

**3. What is a perimeter example?**

The perimeter is the distance around the object. For example, your house has a fenced yard. The perimeter is the length of the fence. If the yard is 30 ft Ã— 30 ft your fence is 900 ft long.
