The correct answer is option 3: 13 m2.
To find the carpet area of the room, we need to calculate the area of the rectangle shown in the diagram. The length of the rectangle is given as 7 meters and the breadth is given as 1.8 meters.
To find the area of a rectangle, we multiply the length by the breadth. So, in this case, the area is 7 meters * 1.8 meters = 12.6 square meters.
Therefore, the carpet area of the room is 12.6 m2.
Alert - correct answer should be 12.6 m2.
