Solution :-
Ken wants to cover a floor with tiles
The dimensions of the floor is 3.6m * 3m
Now,
The tiles are 300mm wide and 600mm long
Therefore,
The dimensions of the tile is 0.3m* 0.6m
According to the question,
We have to find the number of tiles which is required to cover the floor
So,
Let the no. of tile be n
Therefore,
n = Area of floor / Area of 1 tile
n = 3.6 * 3 / 0.3 * 0.6
n = 360 * 30 / 30 * 6
n = 36 * 5 / 3
n = 12 * 5
n = 60
Hence, The no. of tiles needed to Ken to cover the floor is 60
