What is the Perimeter of a Rectangle?

The formula for the perimeter of a rectangle is 2 X (L + W), where L is the length and W is the width of the rectangle. For example, given: Length of the rectangle is 5 cm and width is 3 cm, then the perimeter of the rectangle will be 2 X (5+3) = 2 X 8=16 cm. Hope it is clear. You can find more information here:
