The Area is the quantity that expresses the extent of a two-dimensional figure or shape, or planar lamina, in the plane. The Area of a simple closed plane curve is the size of the region enclosed by the curve. The Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape or the amount of paint necessary to cover the surface with a single coat.

**In this topic, we shall study the Area of different figures and theorems associated with them.**

Polygon is Area of a triangle and Area of a parallelogram.

**Polygon:-**

Area of the polygonal region can be expressed as the union of a finite number of triangular regions in a plane such that intersection of any two of these is either a point or a line.

Area of polygon ABCDE = area of ΔBCD + area of ΔABD + area of ΔADE
