Composite Figures

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 11

Solution:

The figure can be divided into a rectangle and triangle as shown below.
