Exploring the Perimeter | Understanding and Calculating the Length of a Closed Figure’s Boundary

Perimeter is a mathematical term that refers to the total length of the boundary or outer edge of a closed figure

Perimeter is a mathematical term that refers to the total length of the boundary or outer edge of a closed figure. It is the sum of all the sides of the figure.

To find the perimeter of a polygon, you simply add up the lengths of all its sides. For example, if you have a rectangle with sides of lengths 5 units and 8 units, the perimeter would be calculated as follows:

Perimeter = Length + Width + Length + Width
= 5 + 8 + 5 + 8
= 26 units

In the case of a circle, the perimeter is called the circumference. It can be found using the formula:

Circumference = 2πr

Here, “r” represents the radius of the circle, and π is a constant value approximately equal to 3.14159.

It’s important to note that the unit of perimeter depends on the unit of measurement used for the sides. For example, if the sides of a rectangle are measured in inches, the perimeter would be in inches as well.

Perimeter is a useful concept in various real-life applications, such as measuring the length of a fence, determining the amount of material required for construction, or finding the distance around a track.
