Answer:
625 ft²
Explanation:
In a square, all of the sides are the exact same length.
We know that one side is 25 feet long, so using the previous knowledge, we know that all of the other sides are also 25 feet long.
To find the area of a square, you multiply two sides together, in this case 25*25
25² or 25*25 equals 625. Don't forget your answer will be feet² because we are finding the area!
