Area of Composite Figures - Circles and Trapezoids

Examples, solutions, worksheets, stories and songs to help Grade 7 students learn how to find the area of composite figures that consist of circles and trapezoids (or trapeziums).

How to find the area of composite figures?
A composite figure or shape consists of two or more shapes.
Step 1: Break the composite shape into smaller parts. Look for rectangles, squares, triangles, circles, and trapezoids.
Step 2: Find the area of each part.
Step 3: Add the areas.
