Instructions:
Have you ever needed to determine the distance around something? The distance around a closed figure is called the perimeter. We determine the perimeter of a closed figure, such as a rectangle, by adding together the dimensions of the sides. To find the perimeter of rectangular objects we can use the formula P = L + W + L + W.
With this interactive application you can determine the perimeter of a rectangular area. To use the application to calculate perimeter, first click on the "play" button and then enter the length and width measurements. After entering the last measurement, be sure to hit the "enter" key. You will notice that the diagram changes to reflect the measurements you enter.
