A) \[(3+2\sqrt{2})\]km
B) \[(3-2\sqrt{2})\] km
C) \[(4+2\sqrt{2})\] km
D) \[(4-2\sqrt{2})\] km
Correct Answer: A
Solution :
: In \[\Delta OAB,\text{ }{{\left( OA \right)}^{2}}+{{\left( AB \right)}^{2}}={{\left( OB \right)}^{2}}\] \[{{\left( OA \right)}^{2}}=16-8=8\] \[OA=2\sqrt{2}\]km Required distance =OC=OA+AC \[=2\sqrt{2}+3\]kmYou need to login to perform this action.
