Exploring the Area of Composite Figures

The video tutorial covers the concept of composite figures, explaining how to decompose them into simpler shapes to calculate areas. It includes practical examples such as calculating the area of rooms from a blueprint, determining the cost of carpeting, and assessing the amount of paint needed for a house. The tutorial also addresses calculating the area of a shaded region and determining if enough spray paint is available for a specific task.

What does it mean to decompose a composite figure?

• To color the figure

• To divide the figure into simpler shapes

• To erase parts of the figure

• To rotate the figure
