Resources
Area of a triangle
Introduce the idea of finding the area of a triangle. Remember this is all about multiplying the base by the height (at right angles to the base) AND then dividing the answer by 2.
Compound Shapes
We are now going look at compound shapes. These are shapes that can be broken down into simpler shapes to allow you to calculate the area.
