in the center of the first sheep of graph paper, draw a figure with straight sides that will fit in a 15 by 20 block (the figure can be hard or easy so I was thinking of going with a simple rectangle). On the second sheet of graph paper draw the same figure with so that is similar to the first rectangle with a 2:1 ratio of the first.
On the 3rd sheet of graph paper draw the same figure again. it should be similar to the first figure but with 3/5 ratio of the first. what sizes should the rectangles be?

Math 
Henry,
L1 = 8
W1 = 4
L2 = 2 * 8 = 16
W2 = 2 * 4 = 8
L3 = (3/5) * 8 = 4.8.
W3 = (3/5) * 4 = 2.4.
