An important question from similarity chapter in which we have to find the length of altitude of a triangle by using basic proportionality theorem if the area of two similar triangles are 36 cm2 and 25 cm2. If an altitude of the first triangle is 2.4 cm.
ML Aggarwal Avichal Publication Class 10, Similarity, question no 4
given two triangles are similar
therefore ratio of their areas =square of ratios of corresponding altitudes
therefore √36/25=2.4/x
impies x=2.88
