You have a tile measuring 40 cm x 40 cm. What is the area of the tile in cm2 and m2?

The tile is a square with sides of $40 \text{ cm}$.
The formula for the area of a square is side $\times$ side.

$$\text{Area} = 40 \text{ cm} \times 40 \text{ cm}$$ $$\text{Area} = 1600 \text{ cm}^2$$

We know that $1 \text{ m} = 100 \text{ cm}$.
Therefore, $1 \text{ m}^2 = (100 \text{ cm}) \times (100 \text{ cm}) = 10000 \text{ cm}^2$.
To convert $1600 \text{ cm}^2$ to $\text{m}^2$, we divide by 10000.

$$\text{Area in m}^2 = \frac{1600 \text{ cm}^2}{10000 \text{ cm}^2/\text{m}^2}$$ $$\text{Area in m}^2 = 0.16 \text{ m}^2$$

The area of the tile is $\boxed{1600 \text{ cm}^2}$ and $\boxed{0.16 \text{ m}^2}$.
