Question

A marble tile measures 10 centimetre x 12 CM how many tiles will be required to cover a Wall of size 3 m into 4 m also find the total cost of The tile at the rate of rupees2 per tile

Answer 1

At first we convert,

Length = 10cm = 10/100 m = 0.1 m
Breadth = 12cm = 12/100 m = 0.12 m

Now,

Area of tile = l x b
=> A = (0.1 x 0.12) m^2
=> A = 0.012 m^2

Again,

Area of Wall = l x b
=> A = (3 x 4) m^2
=> A = 12 m^2


No. of tiles = Area of wall/Area of tiles

=> No. of tiles = 12/0.012

=> No. of tiles = 1000

Now,

Cost of 1 tile = 2

=> Cost of 1000 tiles = Rs (2 x 1000) = Rs 2000
