Question

In the above figure triangle ABC ~triangle PQR find QR .AB=6cm,BC=4cm, CA=5cm .RP=2.5cm, PR=3cm,QR=?​

Answer 1

Answer:

2cm

Step-by-step explanation:

In triangle ABC and triangle PQR

ABC~PQR

therefore AB=PR

BC=QR

CA=RP

SO, therefore AB/PR=6/3

which is equal to 2/1

similarly in CA/RP =5/2.5

=2/1

therefore in BC/QR=4/QR

=>4/QR=2/1

=>BY CROSS MULTIPLICATION

=>QR=4/2

QR=2
