Question

If the ratio of the sides of two equilateral triangles is 3:5,

what is the ratio of the area of the smaller triangle to the
area of the larger triangle?

Answer 1

9 : 25

Explanation:

Given the ratio of the sides of 2 similar equilateral triangles = a : b , then

the ratio of their areas = a² : b²

Given ratio of sides = 3 : 5 , then

ratio of areas = 3² : 5² = 9 : 25
