Two similar triangles have areas in the ratio of 49:81. What is the ratio of their corresponding altitudes?
Show answer & explanation
Correct answer: D
Explanation
Ratio of the areas of similar triangles = 49 : 81
Ratio of the areas in similar triangles = (Ratio of sides or altitudes)²
Ratio of sides / altitudes = √(49 : 81) = 7 : 9
