Question

A room is 13 m long and 9 m broad. Find the cost of carpeting the room with a carpet 75 cm
broad at the rate of 65 per metre.
​

Answer 1

Answer:

Given 

Length of the room =13 m

Breadth of the room =9 m

Area of the room = (length \times breadth)

=(13×9) m2

=117 m2

Let the length required of the carpet be x m

Breadth of the carpet =75 cm=0.75 m

Area of the carpet =(0.75×x) m2

=0.75x m2

For carpeting the room

Area converted by the carpet  = Area of the room

0.75x=117

x=117/0.75

x=156 m

Hence, length of the carpet =15 m

1 m carpet cost = rupees 65

156 m carpet cost will be =(156×65)

= Rupees 10140

Answer 2

Answer:

10,140 Rupees
