Enter the total perimeter length (in) and the total area (in^2) into the Perimeter Ratio Calculator. The calculator will evaluate and display the Perimeter Ratio.

## Perimeter Ratio Formula

The following formula is used to calculate the Perimeter Ratio.

PRR = PL / TA
• Where PRR is the Perimeter Ratio (1/in)
• PL is the total perimeter length (in)
• TA is the total area (in^2)

To calculate the perimeter ratio, divide the perimeter length by the total area.

## How to Calculate Perimeter Ratio?

The following example problems outline how to calculate Perimeter Ratio.

Example Problem #1:

1. First, determine the total perimeter length (in).
• The total perimeter length (in) is given as: 50.
2. Next, determine the total area (in^2).
• The total area (in^2) is provided as: 600.
3. Finally, calculate the Perimeter Ratio using the equation above:

PRR = PL / TA

The values given above are inserted into the equation below and the solution is calculated:

PRR = 50 / 600 = .0833 (1/in)

Example Problem #2:

For this problem, the variables required are provided below:

total perimeter length (in) = 70

total area (in^2) = 800
