2. If ∆ABC ~ ∆DEF, BC = 3EF, and area (∆ABC) = 117 cm² then find area (∆DEF).
3. If ∆ABC and ∆DEF are similar triangles such that angle A = 45° and angle F = 56°, then find angle C.
4. If the ratio of the corresponding sides of two similar triangles is 2:3, then find the ratio of their corresponding attitudes.
5. Perimeter of two equilateral triangles ABC and PQR are 144 m and 96 m, find ar (∆ABC):ar (∆PQR).
