Counting Unit Squares in Rectangles

In this video, Mr. J explains how to find the area of a rectangle by tiling it with unit squares. He demonstrates this method through four examples, each with different side lengths, and shows how to calculate the area by counting the unit squares. The video concludes with a summary of the tiling method.

What is the primary method used to find the area of a rectangle in this video?

• Using a calculator

• Measuring with a ruler

• Using a formula

• Tiling with unit squares

How many unit squares cover a rectangle with side lengths of 4 feet and 3 feet?
