Perimeter
Perimeter is defined as the sum of all the sides of any polygon. The perimeter of any figure is the sum of the length of all the boundaries of that figure. Perimeter of any figure gives us the length of all the boundaries we can understand this by the following example, suppose we have to find the length of wire required to fence a square then the perimeter of the square field gives the required result as it gives the length of the boundary of the square field.
In this article we will learn about Perimeter, how to calculate the perimeter, various formulas used to calculate the perimeter, examples of the perimeters, and others in detail.
