Question

how many square tiles of side 20cm would fit into a rectangular floor of length 6m and breadth 4m?

Answer 1

Heya friend!!
Rajdeep here...

For rectangular floor,
Length = 6m = 6 x 100 cm = 600 cm
Breadth = 4m = 4 x 100cm = 400cm
So area of the floor = l x b
= 600cm x 400 cm = 240000$cm^{2}$

Now, side of one square tile = 20cm
So area occupied by one square tile = 20cm x 20cm = 400$cm^{2}$

Thus, Number of square tiles = Area of floor/Area of 1 tile
= 240000/400
= 600 tiles

Hope my answer is satisfactory...
Thanks!!

Answer 2

Area of one tile=s*s
=20*20
=400cm
Area of floor=l*b
=600*400
=240000
No. Of tile=area of floor/area of a tile
=240000/400
=600tiles
Thnkss:))
