Question

Which transformation would result in the area of a polygon being different from the area

of its pre-image?

A ) Dilated by a scale factor of one

b) Dilated by a scale factor of 2.5

C ) Rotated 270° counterclockwise about the origin

D) Translated four units up and two units to the right​

Answer 1

B) Dilated by a scale factor of 2.5

Explanation:

Dilation is multiplying the size of the polygon which would be changing the area. The reason A is wrong because multiplying anything by 1 doesn't change it.
