Calculating the Area of the Room and the Useful Area

To calculate the area of the room and the useful area, we can use the provided dimensions and information.

a) Area of the entire room: The area of the entire room can be calculated by multiplying the length and width of the room. The given dimensions are 9m x 2m, so the area of the entire room is: 9m x 2m = 18m².

b) Area occupied by the beam: The area occupied by the beam is given as 3m. Therefore, the area occupied by the beam is: 3m².

c) Useful area: To find the useful area, we subtract the area occupied by the beam from the total area of the room: Useful area = Area of the entire room - Area occupied by the beam Useful area = 18m² - 3m² = 15m².

So, the useful area is 15m².

Therefore, to cover the room with linoleum, the worker would need a piece of linoleum with an area equal to the useful area, which is 15m².
