The dilated figure is larger than the original figure if the dilation factor is greater than 1 and the dilated figure becomes smaller than the origial figure if the dilation factor is less than 1.
Since, the dilation factor is 2, the dilated image is larger than the original figure two times.
For the coordinate (x,y) in original figure, the coordiante in the dilated figure will be (2x,2y).
