How To Calculate The Border Area Your Self

Calculating the area is rather simple when you know the formula presented above. Follow these steps:

  1. Write down this formula:

  2. Then change the following variables with your values:
    1. l1 shall be changed with the Outer length of your border. As an example l1 could be changed to 10.
    2. l2 shall be changed with the Inner length of your border. As an example l2 could be changed to 10.
    3. w1 shall be changed with the Outer width of your border. As an example w1 could be changed to 10.
    4. w2 shall be changed with the Inner width of your border. As an example w2 could be changed to 10.
  3. Now you can enter this in to your calculator and you will get your answer.
