The areas of two equilateral triangles are 27 yd2 and 75 yd2. Find the ratio of their perimeters.
2 answers:
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.
3 : 5; 3 : 5 <==ANSWER
Answer:
3:5
Step-by-step explanation:
The areas of two equilateral triangles are 27 square yards and 75 square yards.
The area of an equilateral triangle with sides length 'a' is given by

Therefore, we have

Now, multiply and divide both sides by 3

Hence, the ratio of perimeters of the given two equilateral triangles is 3:5
