# Calculate The Perimeter Of A Square

Last updated: Saturday, June 24, 2023

The perimeter of a square is the total distance around its boundary or the sum of the length of all its sides. Since a square has four sides of equal length, the perimeter is simply four times the length of one of its sides. For example, if a square has a side length of 5 units, its perimeter would be 4 x 5 = 20 units.

The concept of perimeter is used in a variety of real-life situations, such as determining the amount of fencing needed to surround a garden or the length of tape needed to wrap around a box. In geometry, the perimeter of a shape is a fundamental measurement that helps in determining other properties of the shape.

The formula for determining the perimeter of a square is defined as:
$$P$$ $$=$$ $$4$$ $$\cdot$$ $$a$$
$$P$$: the perimeter of the square
$$a$$: the length of any side
The SI unit of perimeter is: $$meter\text{ }(m)$$
