Question

Polygon b is a scaled copy of polygon a using a scale factor of 5. How many times as large is the area of polygon b compared to the area of polygon a?

A) 5 times
B) 10 times
C) 15 times
D) 25 times

Answer 1

The area of polygon b is 25 times larger than the area of polygon a.

Step-by-step explanation:

The area of polygon b is 25 times larger than the area of polygon a.

To find the ratio of the areas, we need to square the scale factor. Since the scale factor is 5, we square 5 to get 25. Therefore, the area of polygon b is 25 times larger than the area of polygon a.
