A dialation stretches or shrinks a figure. The image created by a dialation is similar to the original figure. The scale factor ( k) of a dialation is the ratio of corresponding side lengths. The center of a dialation is a fixed point in the plane about which all points are expanded or contracted. The dimensions of the model of a multi-storey building are 1.2 m X75 cm X 2 m. If the scale factor is 1:30, what is the actual dimensions of the building?
