Homework Help: Geometry - Transformations and Dilations

Posted by Knights on Thursday, February 21, 2013 at 9:32am.

When a square of area 4 is dilated by a scale factor of k, we obtain a square of area 9. Find the sum of all possible values of k.

I do not understand...it is not 3/2, as I was told, but I don't understand why? Help?

4*k = 9
k = 9/4

(9/4) * 4 = 9.
