Correct option is

D

32, PQ =9 cm, PR =12 cm.

Since, △ABC is enlarged to △PQR

hence, △ABC∼△PQR

or ratio of sides = PQAB=QRBC=PRAC

ratio of sides = PQ6=1812=PR8

ratio of sides = 32

and PQ=9 cm and PR=12 cm

Answer 2

Answer:

Explanation:

Let QR = x

ABC and PQR are similar triangles

AB/PQ = BC/QR

12/9 = 9/x

x = 9 × 9/12

x = 6.75

QR = 6.75
