3. Example
Q1. A farmer has a rectangular field that measures 8.7km long and has a total area of 125km2 . What is the width of his field? Test taking strategy Answer

4. Compound Shape Example

5. Test taking Strategy (1 shape)
Write down the information you are given
Write down the appropriate formula
Substitute and Solve

6. Test taking Strategy (Compound Shapes)
Situation 1: Two or more compound shapes added together Situation 2: Find the shaded region by finding the area of one shape minus the other.

7. Area Perimeter and Volume
You will not be given the formulae. At home make a table of the formulae we learned in class and use them enough to remember them.

8. Formulae to get your started

9. Volume
To find the Volume of any Prism do the following. Find the area of the face of the prism and multiply by the length.

10. Surface Area of Cuboid

11. Example Question
a) Draw the net of the cuboid b) What is the volume and Surface Area of this Cuboid?

12. Volume = 2x3x6
= 30cm3
Surface Area = 2(2x3) + 2(2x6) = 2(3x6)
= 72cm2
