Step-by-step explanation:
Area of floor = length ×width
Area of floor = 9 ×6 = 54 m^2
Area of a tile = 15 cm ×15cm
= (15/100) m ×(15/100) m
= 225/10000 m^2
Number of tile required to cover floor = floor area / tile area
Number of tile required to cover floor = 54 / (225/10000)
= 540000/225
= 2400 tiles
Cost of one tile = Rs 4.5
cost of 2400 Tiles = 2400 ×4.5 = Rs 10800
