Triangles ABC and DEF are similar. It is known that AB=6 cmAB = 6\,\text{cm} and DE=9 cmDE = 9\,\text{cm}. The area of △DEF\triangle DEF is 180 cm2180\,\text{cm}^2. (i) Find the scale factor from △ABC\triangle ABC to △DEF\triangle DEF. (ii) Determine the area of △ABC\triangle ABC. (iii) If the altitude drawn from vertex A to side BC measures 4 cm4\,\text{cm}, calculate the corresponding altitude drawn from vertex D to side EF.
