what is the area of ABCDE? What's the area of the larger image ?
From the menu to the left, what is the area of ABCDE? What's the area of the larger image (it might be named poly1')? Divide the larger area by the smaller area, and explain your result

Using information from
N = 5 sides
S = 1 unit
A = (0.5) / Tan( 37 degrees) = 0.37677
Area = (N * S * A ) / 2 = 0.941943
This is for the small one.
The large one has a side 3.5 X the small one so since the area is (3.5)^2 = 12.25 times large
Then the large area is 12.25 * 0.941943 = 11.5388 units^2
We know that the area of the large / small is 12.25 or (3.5)^2 because the area is proportional to the square of the linear length change.
