How will you describe the position of a table lamp on your study table to another person?

In order to describe the position of a table lamp on the study table, we will take two lines, a perpendicular and horizontal assuming the table as a plane and taking perpendicular line as Y axis and horizontal as X axis. Now, take one corner of table as origin where both X and Y axis intersect each other. Then, the length of table Y axis and breadth is X axis from the origin.

Join the line to the lamp and mark a point. Calculate the distance of this point from both X and Y axis and then write it in the form of coordinates.

Let the distance of point from X axis is x and from Y axis is y then the position of the table lamp in terms of coordinates is (x, y)
