A) \[\sqrt{5}\] units
B) \[2\sqrt{5}\] units
C) \[3\sqrt{5}\] units
D) \[4\sqrt{5}\] units
Correct Answer: B
Solution :
| The coordinates of seat of Golu and Monu are \[(3,6)\] and \[(5,2)\]respectively. |
| Distance between Golu and Monu |
| \[=\sqrt{{{(5-3)}^{2}}+{{(2-6)}^{2}}}\] |
| \[=\sqrt{{{(2)}^{2}}+{{(-4)}^{2}}}=\sqrt{4+16}\] |
| \[\sqrt{20}=2\sqrt{5}\]unit |
| So, option [b] is correct. |
