Question

If ABC∼ PQR, AB=4 cm, BC=6 cm, AC=7 PQ=12 cm then find ,PR

Answer 1

Step-by-step explanation:

Since, △ABC is enlarged to △PQR

hence, △ABC∼△PQR

or ratio of sides =

PQ

AB

=

QR

BC

=

PR

AC

ratio of sides =

PQ

6

=

18

12

=

PR

8

ratio of sides =

3

2

and PQ= 12 cm and PR= 25cm
