If the altitude of two similar triangles are in the ratio 2:3, what is the ratio of their areas?
Area of Triangle ∝ Height of triangle
as Area=12base∗height
Since the Triangle are Similar
Ratio of all sides of both Triangles will be same
Hence, h1h2=b1b2=23
So, Ratio of Area =12h1b112h2b2=h1h2∗b1b2=23∗23=49
