Incredible Stretching Square

This is a cool trick we learned today in our class "The Joy of Thinking" by The Teaching Company. You can see that the top square is 8 units by 8 units making the area 64 units. But when we change this square to a rectangle you can see that it now shows the side as 13 units by 5 units making the area 65 units!
