Directions: Q. 1 to 5 |
Malika and Karishma are friends living on the same street in Govindpuri. |
Karishma's house is at the intersection of one street with another street on which there is a temple. They both study in the same school and that is not far from Karishma's house. |
Suppose the school is situated at the point O, i.e., the origin, Malika's house is at P Karishma's house is at Q and temple is at R. |
Based on the above information, answer the following questions. |
A) 3 units
B) 4 units
C) 5 units
D) 2 units
Correct Answer: B
Solution :
In the figure, the coordinates of points are P(4, 6), Q(4, 2) and R (8, 2). |
Given, Malika's house is at P (4, 6) and Karishma's house at Q,(4, 2) |
\[\therefore\] Required distance = PQ |
\[=\sqrt{{{\left( 2-2 \right)}^{2}}+{{\left( 4-4 \right)}^{2}}}\] |
\[=\sqrt{16+0}=4\] units |
