Look at the generic rectangle below.

  1. What two numbers are being multiplied using this rectangle? How can you tell?

  2. Write the product as a sum of the areas and find the answer.

    Look back at problem 3-63 if you are not sure about using generic rectangles.

    We can see that is a factor of both and , so we can put it on the diagram as shown.
    Then we can see that belongs at the top.

    Again, reference problem 3-63 as a guide for this problem. Remember that you are adding the smaller areas to find the total area.
