Lets say our given rectangle measurements for our perimeter are, length = 10, width = 10. We know multiplying these numbers we will get 100. Now making two smaller rectangles that equal the SAME perimeter as a 10 by 10 rectangle, we get a 5 times 5 rectangle. Lets say both smaller rectangles both have side lengths of 5. 5 times 5 is 25, and adding those two rectangles we get 50 instead of 100. (10*10=100) does not equal (5*5)(2)=50
