The problem asks for the area of a square with a side length of 5 feet. The area $A$ of a square is given by the formula:

$A = s^2$

where $s$ is the length of one side of the square.

Given $s = 5$ feet:

$A = 5^2 = 25 \text{ square feet}$

Thus, the correct answer is 25 square feet.

Here are five related questions for practice:

1. What is the perimeter of the square with a side length of 5 feet?
2. How do you find the area of a rectangle if the sides are different lengths?
3. If the side of the square was doubled, what would the new area be?
4. What is the area of a square with a side length of 10 feet?
5. How does the area of a square change when the side length is tripled?

Tip: Remember, the area of a square grows quadratically with the side length, meaning if the side doubles, the area quadruples!
