Perimeter of Two Similar Objects

Subject: Rectangle vs. square area and perimeter

Why do you lose area in a 4 X 12 rectangle as compared to an 8 X 8 
square?  Each has the same perimeter. Thanks.

Hi! What a cool question you've asked us.  For the example you give, 
what I would do would be to draw two rectangles of those 
dimensions.  Then I would mark out 4X4 squares in each.  (I would 
draw this on screen, but it's really much easier on paper...)

How many do you get in the 4 X 12 rectangle?  How many in the 8 X 
8?  Any conclusions?

Write back if you have more questions.
