Question

Polygon ABCD is dilated by a certain scale factor with the origin as the center of dilation to form the image A'B'C'D'. If the length of and are 5.6 units and 2.24 units respectively, what is the value of the scale factor?
0.2
0.4
3.36
2.5

Answer 1

The value that is being asked for in the question is 0.4. If the polygon is dilated into 2.24 units and its length would be 5.6 units originally, then the value of the scale factor should be .4. I got this through multiplying 5.6 units to each of the choices below, and the one that yielded 2.24 units exact is 0.4.
