Question

A room is 4m long and 3m 25cm wide . How many square metres of carpet is needed to cover floor of the room

Answer 1

square meter required to covered the fllor =
4×3.25
=14

Answer 2

Answer:

$6.5m^2$

Step-by-step explanation:

Length = 2m

Width = 3m 25 cm

Since 100 cm = 1 m

So, 1 cm = 0.01 m

So, 25 cm = 0.25 m

Thus the width = 3 m+0.25 m = 3.25 m

Now to find the area of carpet required .We are supposed to find the area of the floor.

Area of floor = $Length \times width$

                    = $2 \times 3.25$    

                    = $6.5m^2$

Hence 6.5 square meters of carpet is needed to cover floor of the room.
