# The areas of two

Answer :

Given: Area of triangle 1 = 25 cm2

Area of triangle 2 = 36 cm2

Altitude of triangle 1 = 3.5 cm

To find: Altitude of triangle 2

Let the altitude of triangle 2 be x.

The areas of two similar triangles are in the ratio of the squares of the corresponding altitudes.

We have,  x = √17.64 = 42 cm
