Answer:
10800
Step-by-step explanation:
The bottom of the pool(area=60*40) and the four walls (area=1.5*40 for two walls and area=1.5*60 for the other two) have to be tiled.
Total area to be tiled = 60*40 + 2*1.5*40 + 2*1.5*60
= 2400 + 120 + 180
= 2700 m^2
Area of one square tile = 0.5*0.5 = 0.25 m^2
Are of n square tiles = 2700 m^2
n = 2700/0.25 = 10800 tiles

Answer:
10800
Step-by-step explanation:
area of swimming pool to be tiled up
= lb + 2h(b + l ]
= 60×40 + 2×1.5(40+60)
= 2700m^2
length of square tile = 50cm = 0.5m
area of tile = 0.5m × 0.5m = 0.25m^2
number of tiles needed
= 2700/0.25 = 10800
