If the ratio of the perimeters of two similar triangles is a : b, what is the ratio of their areas?
Show answer & explanation
Correct answer: B
Explanation
Ratio of the perimeters of two similar triangles = a : b
Ratio of the sides in similar triangles = Ratio of the perimeters
Ratio of the areas = (Ratio of the sides)²
Ratio of the sides = a : b
Ratio of the areas = a² : b²
