Question

find the high of the wall whose length 54m and which can be covered by 2400 tile of a size 25 cm by 20 cm

Answer 1

2.22m will be the height
area of 1 tile=0.25*0.2=0.05m^2
area of 2400 tiles=0.05*2400=120m^2
area of wall =54*x=120
=>x=2.22m

Answer 2

First of all area of tiles is 25×20=500cm^2
total 2400 tiles can be fitted
So, total area is 500×2400=1200000cm^2
Now, by dividing the given length of the wall from entire are we will get height of the wall
That is ,
1200000/54=22222.2222 cm
Hope it help..!!!
