## Basics on the topicComposite Area Problems

After this lesson, you will be able to find the areas of partial regions of composite shapes.

The lesson begins by teaching you that composite figures can be decomposed into smaller shapes. It leads you to learn how partial areas can be found by adding or subtracting the areas of these shapes. It concludes with a few strategies for determining missing values in composite area problems.

This video includes key concepts, notation, and vocabulary such as composite figures (shapes composed of smaller shapes), and partial areas (areas often represented as the shaded region in a composite shape).

Before watching this video, you should already be familiar with the formulas for the areas of various regions, including quadrilaterals, triangles, circles, and semicircles. You should also know how to use composition and decomposition to find the areas of shapes.

After watching this video, you will be prepared to learn how to determine the areas of complex partial and composite shapes.
