To get from C to A, you go 1 across and 2 up? How much do we need to travel to get from R to P?

Follow these steps:

take the initial shape and apply the first transformation (the 90 degree rotation) and draw a light sketch of this shape (im gonna call this X) on the diagram. Then connect the corresponding vertices of the final shape and that of X with straight lines. So now you should have three lines that cross at a single point- this is the Centre of enlargement. You can figure out the the scale factor is (take care with signs as shape is inverted)
