Q8 of 42 Page 214

The areas of two similar triangles are 81cm2 and 49cm2 respectively. If the attitude of the bigger triangle is 4.5 cm. Find the corresponding attitude of the smaller triangle.

Given, area of two similar triangles as 81cm2 and 49cm2


Altitude of the bigger triangle is 4.5cm


Need to find out the corresponding altitude of the smaller triangle


⇒ Δ ABC = Δ DEF


⇒ AP and DQ are corresponding altitude of triangle


⇒ =


⇒ =


⇒ =


⇒ =


⇒ =


⇒ = DQ


⇒ DQ = 3.5cm


Hence, the altitude of similar triangle is 3.5cm
