Answer 1

Step-by-step explanation:

Given -

Length of the room =13 m

Breadth of the room =9 m

Area of the room = (length \times breadth)

=(13×9) m  

2

 =117 m  

2

 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) m  

2

 =0.75x m  

2

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
