Question

A room is 5m 40cm long and 3m 75cm wide. Find the area of the carpet needed to cover the floor

Answer 1

Length of the room =5m 40cm =540 cm
Breadth of the room =3m 75cm = 375 cm
Area of the room = L X B


$540 \times 375 = 202500$
Hence the area of the carpet will be 202500cm = 2025m

Answer 2

The area of the carpet needed to cover the floor is 20.25 m².

Step-by-step explanation:

Given : A room is 5m 40cm long and 3m 75cm wide.

To Find : The area of the carpet needed to cover the floor ?

Solution :

The length of the room is 5m 40cm.

Converting cm into meter,

1 cm = 0.01 m

40 cm = 0.4 m

So, length became 5+0.4=5.4 meter.

The breadth of the room is 3m 75cm.

Converting cm into meter,

1 cm = 0.01 m

75 cm = 0.75 m

So, breadth became 3+0.75=3.75 meter.

The area of the carpet needed to cover the floor is

$A=l\times b$

$A=5.4\times 3.75$

$A=20.25$

Therefore, the area of the carpet needed to cover the floor is 20.25 m².
