In geometry, the perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape. It is measured in linear units of measurement like centimeters, meters, inches, or feet. Let’s try to calculate the perimeter of the following shape: Perime...
Perimeter of a Regular Shape
We know that the length of each side of a regular polygon is the same. Therefore, Perimeter of regular polygon = sum of all its sides = number of sides ✕ length of one side. For example, look at the given regular pentagon. The perimeter of the given regular pentagon can be calculated as follows: Number of sides = 5 Length of one side = 4 cm Therefore, Perimeter = number of sides ✕ length of one side = 5 ✕ 4 = 20 cm The given table summarizes the formulas to find the perimeter of some regular...
Perimeter of An Irregular Shape
Since the sides of an irregular polygon may not all be the same in length, we use the general formula to find the perimeter of an irregular shape. Therefore, Perimeter of irregular polygon = sum of all sides.
We often use the concept of perimeter in real life. For example, when putting up Christmas lights around the house or when we want to put a fence around the backyard, we find its perimeter to know the length of wire we will need.
Example 1: What is the perimeter of the given figure? Solution: We know that the perimeter of a triangle is given by Perimeter = a + b + c, Where a, b, c = length of three sides. Therefore, For the given triangle, Perimeter = 5 cm + 4 cm + 3 cm = 12 cm Example 2:Calculate the perimeter of the following figure. Solution: The given shape is an irregu...

Perimeter is the distance around a two-dimensional shape. Learn how to calculate the perimeter of different shapes, such as triangles, squares, rectangles, circles, sectors and ellipses, with formulas and examples.
Perimeter is the outer edge of an area or the length of the outer edge of a shape. Learn how to use perimeter in different contexts, such as geometry, basketball, and irrigation, with examples and collocations.
A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference . Calculating the perimeter has several practical applications. A calculated perimeter is the length of fence required to surround a yard or garden.
