It depends on the shape, whether it gives you the dimensions or not, or whether you can divide it up into separate shapes.
With some effort. You find the perimeter of each relevant section and add them all together.
You need to break down the composite figure into simpler shapes whose areas you can calculate using appropriate formule and then add together the areas of all the individual bits.
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 20Find 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.
A composite bar chart is whereby each bar displays multiple data points stacked in a single row or column. On the other hand multiple bar graph are usually placed side by side and use different shapes to contrast between them.
