# Area of a Polygon

Polygons are two-dimensional figures which are made of straight line segments and each segment is connected with two other segments at each of its end points. The polygon could be regular or irregular. Polygons are called as
regular when all the angles and sides are equal. If the angles and sides
are not equal then such polygon's are known as irregular polygon.

**The following figures show us some of the different shapes of polygon:**

The total space within the boundary of the polygon is the area of polygon. The area of a polygon can be calculated using the length of the inradius, perimeter, number of sides and circumradius.
