2 × (Plot length [m] + Plot width [m]) − Gates and openings [m]
Understand the inputs
- Plot length
- Unit: m. Use a measured value or your own assumption.
- Plot width
- Unit: m. Use a measured value or your own assumption.
- Gates and openings
- Unit: m. Use a measured value or your own assumption.
Assumptions and limitations
