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. |
