A square metre is equal to 10,000 square centimetres. Since a 40 cm square tile has an area of 1,600 square centimetres (40 cm x 40 cm), you can divide 10,000 by 1,600 to find out how many tiles fit into a square metre. This calculation shows that 6.25 tiles make up a square metre, so you would need 7 tiles to cover the entire area, accounting for any cuts or waste.
