The areas of two equilateral triangles are 27 yd2 and 75 yd2. Find the ratio of their perimeters.

If the areas of two equilateral triangles are 27 yd² and 75 yd², then the ratio of these areas is 27/75 = 9/25 

If the ratios of the areas are 9:25, then their similarity ratio and the ratio of their perimeters is √9:√35 = 3:5.
