Answer» Triangles ABC and DEF are similar. (i) If area (∆ABC) = 16 cm2, area (∆DEF) = 25 cm2 and BC = 2.3 cm, find EF. (ii) If area (∆ABC) = 9 cm2, area (∆DEF) = 64 cm2 and DE = 5.1 cm , find AB. (iii) If AC = 19 cm and DF = 8 cm, find the ratio of the area of two triangles. (iv) If area (∆ABC) = 36 cm2, area (∆DEF) = 64 cm2 and DE = 6.2 cm, find AB. (v) If AB = 1.2 cm and DE = 1.4 cm, find the ratio of the areas of ∆ABC and ∆DEF. |
