Polygon b is a scaled copy of polygon a using a scale factor of 5. how many times larger is the area of polygon b than the area polygon a?

We know that

[Area of Polygon B]=[scale factor]²*[Area of Polygon A]
[scale factor]=5
so

[Area of Polygon B]=[5]²*[Area of Polygon A]

[Area of Polygon B]=[25]*[Area of Polygon A]

the answer is
 the area of Polygon B than the area Polygon A is 25 times larger 

Ithink the answer is c just trying to others

Ineed with this same question!
