Question

How many tiles, having 100 c.m. length and 90 c.m. width , will be required to pave a corridor which is 60 m long and 6 m broad

Answer 1

Area covered by one tile=l×b
=100×90
=9000 cm^2
We will change 60m and 6m in cm
So,
Area covered by corridor =l×b
=6000×600
=3600000cm^2
Tiles required=area covered by corridor /area covered by each tile
=3600000/9000
=400
400 tiles are required
