Final answer:
The perimeter of a square is equal to 4 times the length of one side.
Step-by-step explanation:
The perimeter of a square in terms of its side length "s" units is:
Perimeter = 4s
A square is a four-sided polygon with all sides equal in length. Therefore, to find the perimeter of a square, we simply add up the lengths of all four sides. Since all sides of the square are equal, we can express the perimeter as 4 times the length of one side, which is "s" units.
