## 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 ($$5,15$$).
