Understanding Square Perimeter

The perimeter of a square is the total distance around its four sides. Since all sides of a square are equal in length, the perimeter is simply four times the length of one side.

Formula: If 's' is the length of a side of the square, then the Perimeter (P) is given by:

P = 4 × s

Example: If a square has a side length of 5 cm, its perimeter is 4 × 5 = 20 cm.

This calculator helps you quickly find the perimeter for any given side length, making it useful for geometry problems, construction, and design projects.
