B: Rs. 10080

C: Rs. 14580

D: Rs. 10000

 

Best Answer

Explanation:

Length of the room =13 m

Breadth of the room =9 m

Area of the room=1× b =13 ×9 =117 aqm

Let the length of the carpet required =l m

Width of the carpet =75 cm=0.75m

Area of the carpet = Area of the room

⇒ι×0.75=117

⇒ι=117 /0.75

⇒ι=156m

Length of the carpet required =156 m

Cost of the carpet per metre = Rs 105

Total cost of the carpet=156×105 =Rs.16380.

Final Answer:

Hence, the correct option is (a) Rs. 16380.
