  11. Tuesday, Feb 11 Chapter 9.6 Area of Composite Figures

  12. Area of Composite Figures Objective: To find the area of composite figures.

  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?

  14. Area of Composite Figures A composite figure is made up of two or more two-dimensional figures.

  15. Area of Composite Figures Can we find the exact area of the polygon below?

  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?

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

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

  19. Area of Composite Figures Can we find the exact area of the polygon below? What is the area of each figure? A = bh = 5 · 2 = 10u² A = = = = = u² The area of the figure is 10 + 7 = 17u²

  20. Area of Composite Figures Find the area of the figure below. Can we divide the figure into two known figures?

  21. Area of Composite Figures Find the area of the figure below. Can we divide the figure into two known figures? What is the area of each figure?

  22. Area of Composite Figures Find the area of the figure below. Can we divide the figure into two known figures? A = 10 · 6 A = = 60in² = = 8in² The area of the original figure is 60in² + 8in² = 68in²

  23. Area of Composite Figures Find the area of the figure. Do this on your own.

  24. Area of Composite Figures Find the area of the figure. Rectangle Area A = 12 · 4 = 48ft² Triangle Area A = = = 12ft² 48ft² + 12ft² = 60ft²

  25. Area of Composite Figures Find the area of the figure. Do this on your own.

  27. Area of Composite Figures 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.

  28. Area of Composite Figures Find the area of the figure. What is the area of the square?

  29. Area of Composite Figures Find the area of the figure. What is the area of the square? A = 12 ·12 = 144cm²

  30. Area of Composite Figures Find the area of the figure. What is the area of the square? A = 12 ·12 =144cm² What is the area of the rectangle?
