The area of a square is 25 cm2, which is equal to its side and perimeter.

The solution of the problem:
The area of a square is equal to the product of its two sides. A square is a geometric shape in which all sides are equal. From the condition of the problem, the area of the square is known, which means that you need to extract the square root from the value of the area, or find a number, when multiplied by the same number we get the number 25. That number will be the number 5.
1. The side of the square is five centimeters.
The perimeter of a square is equal to the sum of its sides.
2. Find the perimeter of the square.
5 + 5 + 5 + 5 = 20 centimeters.
Answer: The side of the square is 5 cm. The perimeter is 20 cm.
