Let's use the area model to find $32\times40$32×40.
Fill in the areas of each rectangle.
What is the total area of both rectangles?
So what is $32\times40$32×40?
Calculate $10\times18$10×18 by completing an area model.
Calculate $26\times39$26×39 by completing an area model.
Use the area model to find $33\times22$33×22.
