Lesson 6: Decompose figures to find area

# 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.

• Is m for meters?
• Yes, m stands for meters, like how ft stands for feet.
• Can you learn this in every boarding school or only certain boarding schools?
• I do not know.Why are you asking? That is my question.Welp that's weird a question on a question?CRAZY

• What happened to the 6 on the bottom? The area should be 48 square meters.
• The `6m` on the bottom became `3m`. For the reason that, if you look at the top of the shape when Sal split it up, there was a `3m` distance at the very top, and when Sal decomposes the shape, he split the `6m` piece into two `3m` pieces resulting in the removal of the `6m` into two `3m`'s instead!

Hope this helps!
• What if there is a triangle mixed in with the shape... how do I solve for that?
• That's gonna be finding an area of a triangle, that will come in higher grades.
• Why haven't they explain what "square meters" means?
• Square meters are a form of measurement, like square feet or squares inches.
