4 lessons

In this lesson, we will be comparing the areas of rectangles and triangles. We will then draw triangles with identical areas to given rectangles.

In this lesson, we will be working out the area of compound shapes that can be deconstructed into triangles and quadrilaterals.

In this lesson, we will be working out the area of circles when provided with a given radius.

In this lesson, we will be looking at working out side lengths of various quadrilaterals and triangles when only given the area and 1 other measure of a shape.
