  • 16. Perimeter<br />The perimeter of a shape is the distance around its edges.<br />
  • 17. Perimeter<br />The perimeter of a shape is the distance around its edges.<br />Example<br />Find the perimeter of this room<br />
  • 18. Perimeter<br />The perimeter of a shape is the distance around its edges.<br />Example<br />To find the perimeter we need to know the lengths of some of the missing sides. The side joining shapes (a) and (b) is 7 in total, but 3 is missing from it so it has a length of 7 -3 = 4.<br />The total perimeter will be:<br />shape (a) 7 + 7 + 7 + 4 = 25<br />shape (b) 3 + 3 +3 = 9<br />total = 25 + 9 = 34 units.<br />Find the perimeter of this room<br />
  • 19. Now try these 1<br />Find the perimeter of the following shapes:<br />(a) (b)<br />4 cm <br /> 6 cm <br />4 cm <br />4 cm <br /> 4 cm <br />2 cm <br />
  • 20. (c) (d)<br />All dimensions in metres<br />
  • 21. The perimeter of a circle<br />The perimeter of a circle is called the circumference.<br />
  • 22. The perimeter of a circle<br />The perimeter of a circle is called the circumference.<br />The circumference = π  diameter or 2  π  radius<br />
  • 23. The perimeter of a circle<br />The perimeter of a circle is called the circumference.<br />The circumference = π  diameter or 2  π  radius<br />Cherry pies delicious <br />
  • 24. The perimeter of a circle<br />The perimeter of a circle is called the circumference.<br />The circumference = π  diameter or 2  π  radius<br />Find the circumference of these circles<br />2 cm 10 cm<br /> 1 m<br />
