Answer:
125 tiles
Step-by-step explanation:
The shape of the tile is square and the length of its side is 20 CM(centimetre)
So,
area of one tile= side*side or side sq.
= 20*20=400
=400CM
The shape of the room's floor is rectangle and as we know area of a rectangle is length*breadth
are of the room's floor = 2.5m(250CM)*2m(200CM)
250*200=50000CM
No. of tiles required = area of the room's floor/area of one tile
= 50000/400=125 tiles
So the no. of tiles required to cover the whole floor are 125.
