Hereis your answer! ! !

Lenght of the room = 12 m

Breadth of the room = 10 m

Area of the room = 12 × 10 = 120 m^2

Lenght of one carpet = Lenght of room

Breadth of carpet = 70 cm = 0.7 m

Area of 1 carpet = 12 × 0.7 = 8.4 m^2

No. of carpets needed = Area of room / Area of 1 carpet

= 120 / 8.4

= 14.2

So,

No. of carpets needed is 14 full lenght and one half lenght carpet.

Cost of one carpet = 60 rs

Total cost = 14.2 × 60 = 852 rs
