14. All composite shapes can be broken down into a collection of simple shapes

16. Do not copy this page down.

17. Composite shapes are used all the time in art and graphic design.

18. Video game design..

19. Superheros…

23. How would you divide this shape up? A rectangle and 2 semi-circles

24. A total = A 1 + A 2 + A 3 A1A1 A2A2 A3A3

25. A1A1 A2A2 A3A3

26. How? A total = A 1 - A 2 A1A1 A2A2

27. 1. Find the area: 10 cm 2 cm 7 cm 10 cm 3 cm 12 cm A = A 1 + A 2 A1A1 A2A2 = 10x2 + 10x3 = 20 + 30 = 50 cm 2

28. 2. Find the area of the grey region 10cm 3 A =  r 2 A y = A 1 - A 2 A y =  (10) 2 -  (3) 2 A1A1 A2A2 A y =  100 -  9 A y = 285.7 cm 2
