Solution:-
Let us observe the figure of a study table with a lamp placed on its surface.
- Consider the lamp as a point on the table.
- Consider the table surface as a plane.
- From a top view, the table appears to be rectangular, consisting of a short edge and a long edge.
To describe the lamp’s position, we measure its distance from both edges:
- Distance from the shorter edge = 10 cm
- Distance from the longer edge = 20 cm
Hence, the position of the lamp on the rectangular table can be represented using coordinate pairs. Depending on which edge is chosen as the x-axis or y-axis, the position can be written as:
- (10, 20) or
- (20, 10)
This demonstrates how the coordinates of a point on a plane depend on the order and orientation of the axes.
Solution:-
Street plan is as given in the above figure:
(i) Therefore, there is only one scross stree, which can be referred to as (3, 4).
(ii) There is only one cross stree, which can be referred to as (3, 4).
