Question

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

Answer 1

Given, length of the room = 13 m.

Given, breadth of the room = 9 m.

We know that Area of the room = length * breadth

                                                     = 13 * 9

                                                     = 117 m^2.

Given, width of the carpet = 75 cm = 0.75 m.

Here, we need to cover the entire area with a carpet of 0.75 m.

Length of the carpet required = Area of room/Width of carpet

                                                  = 117/0.75

                                                  = 156 m.

Given, cost of 1 m carpet = 105.

Cost of 156 m carpet = 105 * 156

                                   = 16380.

Therefore, cost of carpet = 16380.

Hope it helps!
