Consider the generic rectangle shown at right.

1. Copy and complete the generic rectangle.

   Hint (a):

   Solve for the empty spaces one by one.
   What is the product of $20$ and $6$?
   Smaller steps like these make completing the whole rectangle easier.

   Partial Answer (a):

   A few of the spaces are filled in to help you get started.

   Generic Rectangle	Top edge left$20$	Top edge right, blank
   Left edge top${\color{red}{40}}$	Interior top left$800$	Interior top right, blank
   Left edge bottom$+6$	Interior bottom left${\color{red}{120}}$	Interior bottom right$18$

2. Write as many products as you can see in the rectangle. Find at least four. For each one, show the factors being multiplied, as well as the product.

   Hint (b):

   One of these products is $20(40)$, which equals $800$.
   Can you find at least three more like it?
   If you are up for a challenge, there are eight more to find.
