Answer:
Rs. 14,875
Step-by-step explanation:
area of room = l × b
= 11.5 × 6.3
= 72.45 sq m
area of one tile
= 23 × 9
= 207 sq cm
or = 0.0207 sq m
total number of tiles required
= area of room/area one tile
= 72.45/0.0207
= 3500 tiles
cost of 1 tile Rs. 4.25
cost of 3500 tiles
= 3500 × 4.25
= 14875
total cost of tiling the room = Rs. 14,875
hope you get your answer
