Answer:
Given, length of the room = 4 m and breadth of the room = 3 m 50 cm = 3 m + 50 cm \[=3m+50\times \frac{1}{100}m\] \[\left[ \because 1cm=\frac{1}{100}m \right]\] \[=3m+\frac{50}{100}m=3m+0.50m=3.50m\] \[\because \] Carpet needed to cover the floor of the room = Area of the floor = Length \[\times \] Breadth \[=4m\times 3.50m=14sqm\] Hence, the carpet needed to cover the floor of the room is 14 sq m.
