A dilation creates an image of the same shape, but of a different size. Dilations are always done with a certain scale factor. Let's look at the image in the picture and determine the length and width of each of the rectangles:

Notice that both the length and the width of the rectangle doubles in the purple rectangle, from the blue rectangle; thus the scale of the dilation is

Notice that both the length and the width of the rectangle triples in the purple rectangle, from the blue rectangle; thus the scale of the dilation is
