A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape).
For example, figure ABCD is a composite figure as it consists of two basic figures. That is, a figure is formed by a rectangle and triangle as shown below.
The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure.
Example 20
Find the area of the following composite figure:
Solution:
The figure can be divided into a rectangle and triangle as shown below.
So, the area of the composite figure is 216 cm2.
