| Directions: Q. 16 to 20 |
| In a cinema hall, peoples are seated at a distance of 1 m from each other, to maintain the social distance due to CORONA virus pandemic. Let three peoples sit at points P, Q and R whose coordinates are (6, - 2), (9, 4) and (10, 6) respectively. |
 |
| Based on the above information, answer the following questions. |
A) \[\sqrt{5}\]units
B) \[4\sqrt{5}\]units
C) \[3\sqrt{5}\]units
D) None of these
Correct Answer: C
Solution :
| Given, coordinates of P (6, - 2) and R (10, 6) |
| \[\therefore\] Required distance |
| \[=\sqrt{{{\left( 6-\left( -2 \right) \right)}^{2}}+{{\left( 10-6 \right)}^{2}}}\] |
| \[=\sqrt{64+16}=\sqrt{80}\] |
| \[=4\sqrt{5}\]units. |
