A room is 4 m long and 3 m 50 cm wide. How many square metres of carpet are needed to cover the floor of the room?

To find out how many square meters of carpet are needed to cover the floor of a room, you can use the formula:

Area = Length × Width

In this case, the length is 4 meters, and the width is 3 meters and 50 centimeters. To calculate the area in square meters, you need to convert the width from centimeters to meters.

1 meter = 100 centimeters

So, 3 meters 50 centimeters is equivalent to 3.50 meters.

Now, calculate the area:

Area = 4 meters × 3.50 meters = 14 square meters

You would need 14 square meters of carpet to cover the floor of the room.
