Question

In triangle PQR, A and B are the points on the sides PQ and PR respectively. If PA = 2.4 cm, AQ =

3.6 cm, PB = 3.2 cm, BR = 4.8 cm, AB = 2 cm. Find QR​

Answer 1

Answer:

First prove the triangles are similar

then PQ/PA=QR/AB

2.4+3.6/2.4=x/2

6/2.4=x/2

6*2/2.4=x

x=12/2.4

x=1/0.2

x=5 cm
