##### LESSON SET
Relate area to the operations of multiplication and addition. Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths. Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.

## Given the area, find missing side lengths of a rectangle

In this lesson, you will learn how to find the side length of a rectangle by drawing an array when the area is known.
