Final answer:
The area of a square with a side length of 25 inches is calculated using the formula a = s², resulting in an area of 625 square inches.
Step-by-step explanation:
The area of a square with side lengths that are 25 inches can be calculated using the formula a = s², where s is the length of one side of the square. Since the side length (s) is given as 25 inches, we simply need to square this value to find the area:
a = 25 inches × 25 inches = 625 square inches.
Therefore, the area of the square is 625 square inches.
