Tip #1
A square has four right angles. It has four sides and all the sides have the same length.

Now, if the length of each side is L, the perimeter, P, of the square will be the sum of the length of each side. Hence:
P = 4L
a square with all sides of length L

The math video below will give more explanation on this. Also, we will see some examples on how to use this formula.
