Q7 of 95 Page 5

In the adjoining figure, DE || BC, AD = 2.4 cm, AE = 3.2 cm, CE = 4.8 cm, find BD.

Given: AD = 2.4cm, AE = 3.2cm and EC = 4.8cm

and DE || BC


Basic Proportionality theorem which states that if a line is drawn parallel to one side of a triangle the other two sides in distinct points, then the other two sides are divided in the same ratio.


So, by basic proportionality theorem






⇒ DB = 3.6 cm


or BD = 3.6 cm
