question

Use the model to find

525

First, find the missing side lengths.

500

Then, find the quotient.

525

solution

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

500

Start with the first rectangle. One side length is 5, and you need to find the other side length. You can multiply the side lengths to get the area, which is 500.

500

Divide to find the missing number.

500

100

So, the missing side length of the first rectangle is

100.

100

500

Now, look at the second rectangle. One side length is 5, and you need to find the other side length. Again, you can multiply the side lengths to get the area, which is 25.

Divide to find the missing number.

So, the missing side length of the second rectangle is

100

500

Finally, redraw the model as one big rectangle. Its area is 500 + 25 = 525. One side length is 5, and the other is 100 + 5 = 105.
