# Calculate The Perimeter Of A Polygon

Last updated: Saturday, June 24, 2023

The perimeter of a polygon is the total length of its sides. To find the perimeter, you simply add up the length of all the sides. The formula for the perimeter of a polygon depends on the number of sides and the length of each side. For example, for a regular polygon (one with all sides and angles equal), the perimeter formula is:

perimeter = number of sides x length of each side

Real-life examples of the perimeter of a polygon include measuring the length of a fence around a property, the boundary of a sports field or running track, or the distance traveled by a polygonal robot.

In mathematics, the concept of perimeter is used in geometry to calculate the distance around a two-dimensional shape, as opposed to the area which calculates the space inside the shape.

The formula for determining the perimeter of a polygon is defined as:
$$P$$ $$=$$ $$n$$ $$\cdot$$ $$s$$
$$P$$: the perimeter of the polygon
$$n$$: the number of the sides
$$s$$: the length of any side
The SI unit of perimeter is: $$meter\text{ }(m)$$
