To find the area of a square, you can use the formula:

$\text{Area} = \text{side}^2$

In this case, the side of the square is given as 5 cm. Therefore:

$\text{Area} = 5^2 = 25 \, \text{cm}^2$

So the correct answer is 25 cm².

1. How do you calculate the perimeter of a square?
2. What would the area be if the side of the square was doubled?
3. How do you find the diagonal of a square if you know the side length?
4. How does the area of a square compare to the area of a rectangle with the same side length?
5. What is the difference between area and perimeter?

Tip: The area of a square grows quadratically as the side length increases (since you square the side length).
