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

**Solution:**

The above figure is a 3-D show of a study table on which a study lamp is placed.

Now let us consider only the top surface of the table, which becomes a 2-D rectangle figure.

From the Figure above,

- Consider the lamp on the table as a point
- Consider the table as a 2-D plane.

The table has a shorter side (20 cm) and a longer side (30 cm).

- Let us measure the distance of the lamp from the shorter and the longer side.
- Let us assume

a) The distance of the lamp from the shorter side is 5 cm.

b) The distance of the lamp from the longer side is 15 cm.

Let's plot this on the cartesian plane as shown below.

Therefore, we can conclude that the position of the lamp on the table can be described with respect to the order of the axes as (5, 15).
