How to Find the Area of Composite Figures Using Rectangles

TL;DR

To find the area of composite figures, divide them into smaller rectangles, calculate the area of each by multiplying length and width, and sum these areas. The approach is flexible; different divisions yield the same total area. Understanding missing side lengths through subtraction can also help in the calculation.

Transcript

in today's lesson we're going to talk about how to calculate the area of a composite figure and we're going to do so using rectangles so just to recap let's say if we have a rectangle with the length L and the width W the area of that rectangle is length time width so for instance let's say we have a rectangle that's 5 in long for in wide the area ...
