Question

a marble tile measures 12 cm into 10cm how many tiles will be required to cover a wall of size 4m by 3m also find the total cost of tiles at ₹22.50 per tile​

Answer 1

Answer:

22,500 rupees

Step-by-step explanation:

length of a wall = 4m

breadth of a wall = 3m

Area of a wall = length*breadth

= (4*3)m^2

=12m^2

length if a tile = 12 cm

breadth of a tile = 10cm

Area of a tile = length*breadth

=(12*10)cm^2

1m^2=(10^4) cm^2 or 10,000cm^2

12m^2=12*10,000cm^2

Therefore,number of tiles = (12*10,000m^2)/(12*10cm^2)

number of tiles = 1000

cost of 1 tile = 22.50 rupees

cost of 1000 tiles =22.50*1000

=22,500 rupees
