Final answer:
The side length of the square is 12 cm and the perimeter is 48 cm.
Step-by-step explanation:
The area of a square is equal to the side length squared. Therefore, to find the side length of the square, we can take the square root of the area. So, in this case, the side length of the square would be √144 cm, which is equal to 12 cm.
The perimeter of a square is given by the formula P = 4s, where s is the side length. So, the perimeter of this square would be 4 times the side length, which is 4 * 12 cm = 48 cm.
