A) 3 units
B) \[3.5\]units
C) \[3\sqrt{5}\] units
D) \[5\sqrt{5}\]units
Correct Answer: C
Solution :
| The coordinates of the vertices P and R are \[(6,9)\]and \[(9,3)\]respectively. |
| \[\therefore \,\,\,\,\,\,\,PR=\sqrt{{{(9-6)}^{2}}+{{(3-9)}^{2}}}\] |
| \[=\sqrt{9+36}=\sqrt{45}=3\sqrt{5}\]units |
| So, option [c] is correct. |
