Question

The side of a square tile is 12 cm.how many tiles can be placed on a floor which is 3.6m long and 2 m wide?

Answer 1

Answer:

Step-by-step explanation:Area is each tile=12cm×12cm=144 sq.cm

Length of floor=3.6m=360cm

Width=200cm

Hence

Area of floor=360×200=72000 sq.cm

So no. of tiles that can be placed there =72000÷144=500 tiles

Therefore the no. of tiles that can be. Placed is 500 tiles

Answer 2

area of the floor = l× b
=3.6×2=7.2 m^2

area of a tile=s×s
=12×12/100×100
=144/10000
0.0144

no. of tiles= area of the floor/ area of a tile
=7.2/0.0144
=500
so
500 tiles are needed
