Answer 2

The area of the carpet needed to cover the room is 211.15 m².

Step-by-step explanation:

Given : A room is 20 m 50 cm long and 10 m 30 cm wide.

To find : The area of the carpet needed to cover the room ?

Solution :

The length of the room is l=20 m 50 cm

Convert cm into m,

1 cm = 0.01 m

50 cm = 0.5 m

i.e. $l=20+0.5=20.5\ m$

The width of the room is l=10 m 30 cm

30 cm = 0.3 m

i.e. $b=10+0.3=10.3\ m$

The area of the carpet needed to cover the room is the area of the room.

Area of the room is given by,

$A=l\times b$

$A=20.5\times 10.3$

$A=211.15\ m^2$

Therefore, the area of the carpet needed to cover the room is 211.15 m².
