Answer:
To be precise, in theory*, you’ll need 300 tiles of 20 x 20 cm.
How? Well each metre would require five 20 x 20 cm tiles laid side-by-side.
So for the length of 4m, you would need 20 (4 x 5) tiles across and for the breadth of 3 m, you would need 15 (3 x 5) tiles across.
So in total you would need 20 x 15 = 300 tiles to cover the floor.
