The area model uses the distributive property to build rectangles for each place being multiplied.
In the example above, we have broken 39 x 4 into (30 x 4) + (9 x 4).
Once the area of each rectangle is found, the partial products are added together.
120 +36= 156
39 x 4 = 156
How can you use an area model to solve 42 x 8?
