How is the perimeter of a square calculated?

The perimeter of a square is calculated using the formula ( P = 4s ), where ( s ) represents the length of one side of the square. This formula is derived from the fact that a square has four equal sides. To find the total distance around the square, you simply add the length of each side together, which results in ( s + s + s + s = 4s ).

This method highlights the unique property of a square: all its sides are of equal length. Consequently, when calculating the perimeter, you do not need to consider varying side lengths, which makes this formula both straightforward and efficient for finding the perimeter of any square.
