- Slide 12
- Objective: To find the area of composite figures.
- Slide 13
- Area of Composite Figures At the end of this lesson you should be able to answer the following question. How do you decompose figures to find the area?
- Slide 14
- Area of Composite Figures A composite figure is made up of two or more two-dimensional figures.
- Slide 15
- Area of Composite Figures Can we find the exact area of the polygon below?
- Slide 16
- Area of Composite Figures Can 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?

- Slide 27
- Find the area of the figure. To find the area of overlapping figures, add the areas of the figures if they were not overlapped and then subtract the overlapped area.
- Slide 28
- Area of Composite Figures Find the area of the figure. What is the area of the square?
- Slide 29
- Area of Composite Figures Find the area of the figure. What is the area of the square? A = 12 12 = 144cm
- Slide 30
- Area of Composite Figures Find the area of the figure. What is the area of the square? A = 12 12 =144cm What is the area of the rectangle?
- Slide 31
- Area of Composite Figures Find the area of the figure. What is the area of the square? A = 12 12 =144cm What is the area of the rectangle? A = 12 15 = 180cm What is the area of both figures?
- Slide 32
- Area of Composite Figures Find the area of the figure. What is the area of the square? A = 12 12 =144cm What is the area of the rectangle? A = 12 15 = 180cm What is the area of both figures? 144cm+180cm=324cm
- Slide 33
- Area of Composite Figures Find the area of the figure. What is the area of the overlapped area? What is the area of both figures? 144cm+180cm=324cm
- Slide 34
- Area of Composite Figures Find the area of the figure. What is the area of the overlapped area? A = 7 6 =42cm What is the area of both figures? 144cm+180cm=324cm What is the total area?
- Slide 35
- Area of Composite Figures Find the area of the figure. What is the area of the overlapped area? A = 7 6 =42cm What is the area of both figures? 144cm+180cm=324cm What is the total area? 324cm - 42cm = 282cm
- Slide 36
