1. Calculate the height (in cm to the nearest integer) of an equilateral triangle whose area is 36.95 cm².   Hint Hint       2. Calculate the side (in cm to the nearest integer) of an equilateral triangle whose height is 10.4 cm.   Hint       3. Calculate the area (in cm² upto 1 decimal place) of an equilateral triangle of side 10 cm.   Hint       4. Find the area (in m²) of an isosceles triangle, each of whose sides is 10 m and base 12 m.   Hint       5. If the area of an equilateral triangle is 36√3 cm², find its perimeter (in cm).   Hint       6. The base of an isosceles triangle is 24 cm and perimeter is 64 cm. Find its area (in cm²).   Hint       7. The base of a triangular field is five times its height. If the cost of cultivating the field at $32 per hectare is $500, find its height (in m). Note that 1 hectare = 10000 m2.   Hint
