Coordinate Geometry

Ex 3.1 | Question 1

## Text Solution

**Steps:**

The above figure is a \(\rm3-D\) shows a study table, on which a study lamp is placed.

Now let us consider only the top surface of the table which becomes a \(\rm2-D\) rectangle figure.

From the Figure Above,

- Consider the lamp on the table as a point
- Consider the table as a \(\rm2-D\) plane.

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

- Let us measure the distance of the lamp from the shorter side and the longer side.
- Let us assume
- Distance of the lamp from the shorter side is \( 5 \rm\;{cm}.\)
- Distance of the lamp from the longer side is \( 5 \rm\;{cm}.\)

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 (\(5,15\)).
