Option C —
14 sq.m
Step-by-Step Calculation:1.Calculate the total area of the floor:
The floor is a rectangle, so its area is length width
{Area of Floor} = 6{ m} times {3{ m} = 18{sq.m}
2. Calculate the area of the square carpet:
The area of a square is side times side{Area of Carpet} = 2{ m} times 2{ m} = 4{ sq.m}
3. Calculate the un-carpeted area:
To find the area not covered by the carpet, subtract the carpet area from the total floor area:
{Un-carpeted Area} = {Total Area} - {Carpet Area} {Un-carpeted Area}
= 18{ sq.m} - 4{ sq.m} = 14{ sq.m}
