Theory:

In the previous topics, we learnt how to apply the formula and found the perimeter and area of the shapes like square, rectangle and triangle.
 
In this topic, we will learn about how to find the perimeter and area of the combined shape using these shapes.
 
What is combined shape?
 
A combined shape is a shape that can be formed by the combination of many different shapes.
Example:

In the above figure, it is clear that the figure is formed by the combination of triangle, square and rectangle.
