### Example Question #1 : Perimeter Of Triangles, Squares, And Rectangles

Find the perimeter of a square with the following side length:

Explanation:

Perimeters can be calculated by adding together the side lengths of a polygon. A square has four sides that are all the same length, therefore, we can write the following formula to solve for the perimeter.

We can rewrite this equation as the following:

In these equations the variable, , represents side length.

Substitute the known side length and solve.
