Q. 8

In the figure given below. If AD = 2.4 cm, DB = 3.6 cm and AC = 5 cm. Find AE.

Answer :


Given DE || BC, AD = 2.4 cm, DB = 3.6 cm and AC = 5 cm.


We have to find AE.


We know that basic proportionality theorem states that if a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, then the other two sides are divided in the same ratio.





2.4 (5 – AE) = 3.6 AE


12 – 2.4 AE = 3.6 AE


12 = 3.6 AE + 2.4 AE


12 = 6 AE


AE = 12/6


AE = 2 cm
