Q13 of 32 Page 6

The areas of two similar triangles are 81 cm2 and 49 cm2 respectively. If the altitude of the first triangle is 6.3 cm, find the corresponding altitude of the other.(CBSE 2001)


Let the two triangles ABC and DEF have their altitudes as AS and DT.


We know that if two triangles are similar then the ratio of their areas is equal to the ratio of the squares of their corresponding altitudes.
