Calculating the area and the perimeter. The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.

It actually depends on the given shape or figure. To sum it all up, finding the perimeter is simply adding all the distance of all the sides a figure has.
