A) \[\text{12}.\text{3 cm}\]
B) \[\text{6}.\text{7 cm}\]
C) \[\text{19}.\text{8 cm}\]
D) \[\text{9 cm}\]
Correct Answer: C
Solution :
| \[Q'R'=3\,QR=3\times 3.5=10.5\,cm\] |
| and \[P'S'=3\,PS=3\times 3.1=9.3\,cm\] |
| \[\therefore \,\,\,\,\,\,\,\,\,\,Q'R'+P'S'=10.5+9.3=19.8\,cm\] |
| So, option [c] is correct. |
