A dilation will map shape II onto shape III. The bottom left coordinate of shape II is (3, 3) and the bottom left coordinate of shape III is (2, 2). So, to get the corresponding coordinates of shape III, multiply the coordinates of shape II by 2/3. This is true for every set of coordinates. So, the scale factor is2/3 . Because the scale factor is less than 1, the dilation is a reduction.
