Composite Figures and Area Calculations

This video tutorial teaches how to calculate the area of composite figures using rectangles. It begins with a basic introduction to the concept and then provides three examples of increasing difficulty. Each example demonstrates how to break down a composite figure into smaller rectangles, calculate their areas, and sum them to find the total area. The video also offers tips on finding missing side lengths and encourages viewers to explore related content for further learning.

What is the formula for calculating the area of a rectangle?

• Length + Width

• Length - Width

• Width / Length

• Length x Width
