Answer:
Step-by-step explanation:
hall:
length = 10.8m = 1080cm
width = 7.5m = 750cm
tiles:
length = 15cm
width = 12cm
Area covered by 1 tile = 15 x 12 = 180cm^2
Area of Hall = 1080 x 750 = 810000 cm^2
Tiles required to cover complete hall = 810000 / 180 = 4500
100 tiles cost 4.1
hence 4500 tiles cost = (4500 x 4.1)/100 = 184.5
