What is the formula for the perimeter of a square?

The formula for the perimeter of a square is P = 4s, where 's' is the length of one side.

In more detail, the perimeter of a square is the total distance around the outside of the square. Since a square has four equal sides, you can find the perimeter by adding up the lengths of all four sides. This is why the formula is P = 4s. Here, 'P' stands for perimeter and 's' stands for the length of one side of the square.

For example, if each side of the square is 5 centimetres long, you would calculate the perimeter by multiplying 5 by 4, which gives you 20 centimetres. This means the total distance around the square is 20 centimetres.

Understanding this formula is quite useful, especially in real-life situations where you might need to measure the boundary of a square garden or a square piece of fabric. It’s a straightforward calculation that can save you a lot of time and effort. Just remember, the key is that all four sides of a square are always equal, which simplifies the process of finding the perimeter.
