question

Use the model to find

112

First, find the missing side lengths.

Then, find the quotient.

112

solution

The model shows a big rectangle made up of two smaller rectangles.

Start with the first rectangle. One side length is 7, and you need to find the other side length. You can multiply the side lengths to get the area, which is 70.

Divide to find the missing number.

So, the missing side length of the first rectangle is

10.

Now, look at the second rectangle. One side length is 7, and you need to find the other side length. Again, you can multiply the side lengths to get the area, which is 42.

Divide to find the missing number.

So, the missing side length of the second rectangle is

Finally, redraw the model as one big rectangle. Its area is 70 + 42 = 112. One side length is 7, and the other is 10 + 6 = 16.
