This document discusses calculating the area of composite shapes made up of squares, rectangles, triangles, and circles at level 2. It provides the formulas for finding the area of rectangles, triangles, and circles. An example problem is given to find the total area of a composite shape made up of a rectangle, triangle, and circle by using the appropriate formulas and adding the individual areas. The key areas covered are the formulas for finding the area of different shapes and an example of calculating the total area of a composite shape by adding the individual areas.
