Finding Area with the Distributive Property

This video tutorial teaches how to find the area of rectangles using the distributive property. It begins with an introduction to benchmark numbers and their role in estimation. The concept of unit squares is explained, followed by basic area calculation through multiplication of rows and unit squares. The lesson progresses to decomposing rectangles using benchmark numbers to simplify area calculations. Examples are provided to illustrate the process. The tutorial concludes with a practical application of calculating the area of posters, reinforcing the learned concepts.

What benchmark numbers can be used to estimate the area of a rectangle?

If Jalen's poster covers 12 square units and Cadence's poster covers 8 square units, what is the total area they cover?
