Polygon d is a scaled copy of polygon c using a scale factor of 6. how many times larger is the area of polygon d than the area polygon c?

The answer is 36

You simply square the linear scale factor 6 and we get 6^2 = 6*6 = 36
You can think of a square with sides of 2 by 2, so the area is 4
If you multiply each dimension by 6, then the square is now 12 by 12 and the new area is 144. Notice how 144/4 = 36, or put another way 36*4 = 144
