If you have 36ft of fencing what are the areas of the different rectangles you could enclose with the fencing? Consider only whole number dimensions.

2 * 18
3 * 12
4 * 9
6 * 6
There are many different areas

1+ 1+17 + 17= 36
1 times 17 = 17

9 + 9 + 9 + 9 = 36
9 times 9 = 81

Look for possibilities between these two.
