Question

A room is 5m long and 4m 50cm wide. How many sq.m of carpet is needed to cover the floor.

Answer 1

Answer:

22.5 m^2

Step-by-step explanation:

Area covers =5 x 4.5 =22.5 m^2

(4 m 50 cm =4.5m)

Answer 2

• Carpet needed = 22.5 m sq. OR 225000 cm sq.

Given:

The length of the room is 5 m = 500 cm

The width (i.e. breadth) of the room is 4m 50 cm = 400 cm + 50 cm = 450 cm

To find:

The carpet needed to cover it

Now,

We need to find the area of the room, then we will get the carpet needed to cover.

The room is a rectangular shape.

The formula to find the area of the rectangle

= length * breadth units sq.

= 500 * 450

= 225000 cm sq.

Now,

Converting it into m sq.

1 m = 100 cm

1 m² = 100 * 100 cm² = 10000 cm²

So,

1 cm = 1/100 m

1 cm² = 1/10000 m²

Thus,

225000/10000 = 22.5 m²

The required carpet which is needed to cover the floor is 22.5 m sq.
