Show answer & explanation
Correct answer: B
Length of the room = 13m
Breadth of the room = 9m
Area of the room = length × breadth
Area = 13 × 9 = 117 m2
Also, we need to cover the entire area with a carpet which is 0.75 m wide.
Hence, length of carpet required = Area of room/width of carpet
= 117/0.75
= 156 m
Cost of 1 m carpet = Rs 12.4
Cost of 156m carpet = Rs 12.4 × 156
= Rs 1934.4
