A) 3 cm
B) 6 cm
C) 9 cm
D) 12 cm
Correct Answer: A
Solution :
[a] \[\Delta PQR\sim \Delta LMN\] \[\therefore \] All sides are proportional to their corresponding sides. \[\frac{PQ}{LM}=\frac{1}{3},\]\[MN=9\,cm\] \[\therefore \]\[QR=\frac{1}{3}\times 9=3\,cm\]You need to login to perform this action.
