Question

find the height of the hall whose length is 4m which and which can be covered by 2400 tiles of size 25cm by 20cm

Answer 1

Answer:

let the height be h.

length=4m=400cm

area of wall=400*h cm²

area of tile=25*20=500cm²

therefore no. of tiles required=2400

∴400*h/500=2400

⇒h= 2400*500/400

     =3000cm=30m

length=30m
