This document provides information on calculating the area and perimeter of basic shapes. It defines key terms like area, perimeter, dimensions, and circumference. Formulas are provided for calculating the perimeter of rectangles, triangles, circles, parallelograms, trapezoids, and the area of triangles, rectangles, parallelograms, trapezoids, and circles. Examples are given for calculating perimeter and area of various shapes. Practice problems are included for applying the formulas.

16. PerimeterThe perimeter of a shape is the distance around its edges.

17. PerimeterThe perimeter of a shape is the distance around its edges.ExampleFind the perimeter of this room

18. PerimeterThe perimeter of a shape is the distance around its edges.ExampleTo 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.The total perimeter will be:shape (a) 7 + 7 + 7 + 4 = 25shape (b) 3 + 3 +3 = 9total = 25 + 9 = 34 units.Find the perimeter of this room

19. Now try these 1Find the perimeter of the following shapes:(a) (b)4 cm 6 cm 4 cm 4 cm 4 cm 2 cm

20. (c) (d)All dimensions in metres

21. The perimeter of a circleThe perimeter of a circle is called the circumference.

22. The perimeter of a circleThe perimeter of a circle is called the circumference.The circumference = π  diameter or 2  π  radius

23. The perimeter of a circleThe perimeter of a circle is called the circumference.The circumference = π  diameter or 2  π  radiusCherry pies delicious

24. The perimeter of a circleThe perimeter of a circle is called the circumference.The circumference = π  diameter or 2  π  radiusFind the circumference of these circles2 cm 10 cm 1 m
