The area $A$ of a square can be calculated using the formula:

$A = s^2$

where $s$ is the length of a side of the square. Given that the side length is 7 cm, the area is:

$A = 7^2 = 49 \, \text{cm}^2$

So, the area of the square is 49 cm².

Tip: The diagonal of a square can be calculated using the Pythagorean theorem: $d = s\sqrt{2}$.
