Question

how many metres of carpet 75cm wide will be required to cover the floor of a room which is 12 metre long and 10 metre wide​

Answer 1

Answer:

the length of room-12m the breadth of room-8m area of room is (L multiply B) =12m multiply 8 m =96m area of room = area of carpet length of carpet= area/breadth 96m/0.75=128m

Answer 2

Step-by-step explanation:

Given:-

A floor of a room which is 12 metre long and 10 metre wide.

To find:-

How many metres of carpet 75cm wide will be required to cover the floor of a room which is 12 metre long and 10 metre wide ?

Solution:-

Length of the floor of a room = 12 m

Width of the floor of the room = 10 m

We know that

Area of a rectangle = length × breadth sq.units

Area of the floor of the room = length× width

=>Area = 12 × 10 sq.m

=>Area = 120 sq.m

Area of the floor of the room = 120 sq.m

Width of the carpet = 75 cm

We know that

1 m = 100 cm

1 cm = 1/100 m

=>75 cm = 75/100 m

=>75 cm = 0.75 m

Now The length of the carpet will be required to cover the floor of the room =

Area of the floor of the room/ Width of the carpet

=>120/0.75

=>120/(75/100)

=>(120×100)/75

=>12000/75

=>160 m

Answer:-

The length of the carpet will be required to cover the floor of the room = 160 m

Used formulae:-

• Area of a rectangle = length × breadth sq.units
• 1 m = 100 cm
