Calculation of Remaining Room Area

To calculate the area of the room that is not occupied by the carpet, we need to subtract the area of the carpet from the total area of the room.

The total area of the room is given as 20 square meters, and the carpet is a square with a side length of 2 meters.

To find the area of the carpet, we can use the formula for the area of a square: Area = side length × side length.

Substituting the given side length of 2 meters into the formula, we find that the area of the carpet is 4 square meters.

To find the remaining area of the room, we subtract the area of the carpet from the total area of the room: Remaining Area = Total Area - Area of Carpet.

Substituting the values, we have: Remaining Area = 20 square meters - 4 square meters.

Therefore, the remaining area of the room that is not occupied by the carpet is 16 square meters.
