Final answer:
The perimeter of a square with a side length of 12 cm is 48 cm.
Step-by-step explanation:
To find the perimeter of a square, we need to know the length of one of its sides. In this case, the side length is given as 12 cm. The perimeter of a square is calculated by multiplying the length of one side by 4, since a square has four equal sides. Therefore, the perimeter can be found by multiplying 12 cm by 4:
Perimeter = 12 cm × 4 = 48 cm
