Question

find the cost of carpeting a room 13m by 9m with a carpet of width 75 cm at rupees 105 per metre

Answer 1

Given the length of the room = 13m.

Given the breadth of the room = 9m.

We know that Area of the room = Length * breadth

                                                     = 13 * 9

                                                     = 117cm^2.


Given width of the carpet = 75cm

                                            = 0.75cm.



Hence length of the carpet required = Area of the room/Width of the carpet

                                                             = 117/0.75

                                                             = 156m.


Given the cost of carpet per meter = 105.

Cost of 156m carpet = 105 * 156

                                   = 16380.


Therefore the cost of carpeting a room = 16380.


Hope this helps!
