Answer 1

Hey dude

Here is your answer

Step-by-step explanation:

Room is rectangle

Iength x breadth

540 x 480 cm (converted m to cms)

Carpet is centrally placed 40cm

So to get length and breadth of carpet reduce 80cm (both side 40cm each ).

Area of Carpet 460cmx 400cm

Convert to Meters. So 4.6m x 4 m

18.4 sq mtrs

Hope it helps you!!

A room of dimension 5.4 metre by 4.8 metre. A carpet is laid centrally leaving a margin of 40 cm all around between the carpet and the walls of the room. Find the area of the carpet in square metres.

______________________________________

Given that :

Dimensions of room are 5.4 and 4.8

Margin of carpet laid on the land is 40cm between carpet and walls.

To find :

The area of the carpet in square metres.

$\huge{\sf{\boxed{\boxed{Solution:}}}}$

As we know that , the room is in rectangular shape.

So,

Length × breadth

540 × 480 cm [We converted metre to centimetre]

40 × 2 = 80

540 - 80 = 460

480 - 80 = 400

Length and breadth of the carpet is 460 and 400 .

Convert them into metres = 4.6 , 4.0.

$\bold{Area:-}$

Area = Length × breadth

= 4.6 × 4.0 = 18.4m^2

$\huge\boxed{Area:-18.4m^2}$
