Area of Composite Figures

In this video, Teacher Guy explains how to calculate the area of composite figures. The tutorial begins with an introduction to the topic, followed by a step-by-step guide on dissecting composite figures into simpler shapes like rectangles. The video demonstrates how to calculate the area of these rectangles and then sum them to find the total area. A more complex example is provided, showing how to use subtraction to find the area of a composite figure. The video concludes with a call to action for viewers to subscribe for more content.
