Answer 2

Step-by-step explanation:

Length of the room =13 m

Breadth of the room = 9 m

Area of the room = L ✖ b = 13 multiply 9 = 117 sq m

Let the length of the carpet required = 'l' m

Width of the carpet = 75 cm = 0.75 m

Area of the carpet = Area of the room

= L ✖ 0.75 = 117

=L = 117/ 0.75

= l = 156 m

length of the carpet required = 156m

cost of the carpet per meter = Rs 105

Total cost of the carpet = 156 multiply 105 = Rs 16380
