A square is one of the most fundamental shapes in geometry, characterized by four equal sides and four right angles. One of the simplest yet most important measurements related to a square is its perimeter. Whether you're a student, a teacher, or just someone needing quick geometry help, this guide will teach you everything about how to calculate the perimeter of a square—plus give you an easy tool: our Perimeter of a Square Calculator!
The perimeter of a square refers to the total length of all four sides. Since all the sides of a square are equal in length, calculating its perimeter is extremely straightforward.
The standard formula to find the perimeter of a square is:
Perimeter = 4 × SideWhere:
Formula:
Perimeter = 4 × 6 = 24 cm
Answer: The perimeter is 24 cm.
Formula:
Perimeter = 4 × 12.5 = 50 meters
Answer: The perimeter is 50 meters.
Formula:
Perimeter = 4 × 8 = 32 inches
Answer: The perimeter is 32 inches.
