Question

A room is 4.20 m long and 3.65m wide.find the area of the carpet needed to cover the floor of the room

Answer 1

Carpet Area = L x B

                    = 4.20 x 3.65

                    = 15.33 m²

Answer 2

15.33

Step-by-step explanation:

As we know

1 m = 100 cm

1 cm = 1/100 m

Length of the room is 4 m 20 cm

= 4+20/100 m

= 4 + 0.20 m

= 4.2 m

Breadth of room is 3 m 65 cm

= 3 + 65/100 m

=3 + 0.65 m

= 3.65 m

Now

Area of floor of the room = Length × Breadth

\begin{gathered} = 4.2 \times 3.65 \\ = 15.33 \: m {}^{2} \end{gathered}

=4.2×3.65

=15.33m

2

Carpet is I Square meter length

So Square meter Carpet required is

= Area of floor/ Area of Square meter Carpet

\begin{gathered} = \frac{15.33}{1} \\ = 15.33m\end{gathered}

=

1

15.33

=15.33m

Therefore 15.33 Square meter Carpet is required to cover the floor of room.
