Area of Composite FiguresArea of Composite FiguresObjective: To find the area of composite figures.

Area of Composite FiguresAt the end of this lesson you should be able to answer the following question.

How do you decompose figures to find the area?

Area of Composite FiguresA composite figure is made up of two or more two-dimensional figures.

Area of Composite FiguresCan we find the exact area of the polygon below?


What if we divided the polygon into two figures we know?

What is the bottom figure?



What is the bottom figure?A rectangle.What is the top figure?



What is the bottom figure?A rectangle.What is the top figure?A trapezoid. What is the area of each figure?

Area of Composite Figures

Area of Composite FiguresFind the area of the figure below.

Can we divide the figure into two known figures?

Area of Composite FiguresFind the area of the figure below.

Can we divide the figure into two known figures?

What is the area of each figure?


Area of Composite FiguresFind the area of the figure.

Do this on your own.






To find the area ofoverlapping figures, add the areas of the figures if they were not overlapped andthen subtract the overlapped area.


What is the area of thesquare?


What is the area of thesquare? A = 12 12 = 144cm


What is the area of thesquare? A = 12 12 =144cm

What is the area of therectangle?



What is the area of therectangle? A = 12 15 = 180cm

What is the area of both figures?



What is the area of therectangle? A = 12 15 = 180cm

What is the area of both figures? 144cm+180cm=324cm


What is the area of theoverlapped area?

What is the area of both figures? 144cm+180cm=324cm


What is the area of theoverlapped area? A = 7 6 =42cm

What is the area of both figures? 144cm+180cm=324cmWhat is the total area?


What is the area of theoverlapped area? A = 7 6 =42cm

What is the area of both figures? 144cm+180cm=324cmWhat is the total area? 324cm - 42cm = 282cm



Area of Composite FiguresFind the area of the figure.Area of the top rectangleA = 6 7 =42ft

Area of the bottom rectangle. A = 6 8 = 48ft

Overlapped area.A = 5 5 = 25ft

Total area is 42ft + 48ft - 25ft = 65ft
