### Course: Class 6 (Old)>Unit 11

Lesson 3: Area of composite figures

# Decomposing shapes to find area: add

Let's find the area of an irregular 10-sided shape by breaking it into smaller rectangles. We'll learn to decompose complex shapes, calculate the area of each rectangle, and combine those areas to find the total area, making the topic engaging and enjoyable. Created by Lindsay Spears.

• I presume you mean the 6m at the bottom.
6m is just the side length of the figure. However, how the area was calculated the 6m was divided into two part (3m each). So the 6m was used as 3m (times 9m) and 3m (times 3m).
