Scale factor is a conversion factor by which the size of a geometrical shape can be changed with respect to its true size. We use scale factor to draw reduced or enlarged shapes of any given figure and to find out the missing area, volume, or length of the reduced or the enlarged figure. We can calculate the scale factor if the dimensions of the original figure and the changed figure are known to us.
