question

Use the model to find

918

First, find the missing side lengths.

900

Then, find the quotient.

918

solution

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

900

Start with the first rectangle. One side length is 9, and you need to find the other side length. You can multiply the side lengths to get the area, which is 900.

900

Divide to find the missing number.

900

100

So, the missing side length of the first rectangle is

100.

100

900

Now, look at the second rectangle. One side length is 9, and you need to find the other side length. Again, you can multiply the side lengths to get the area, which is 18.

Divide to find the missing number.

So, the missing side length of the second rectangle is

100

900

Finally, redraw the model as one big rectangle. Its area is 900 + 18 = 918. One side length is 9, and the other is 100 + 2 = 102.
