What to enter
| Input | Meaning and units |
|---|---|
| D1 (length) | Enter d1 in length; use the same basis as the other measurements. |
| D2 (length) | Enter d2 in length; use the same basis as the other measurements. |
Understanding your result
Read area (length^2), side (length), perimeter (length) in the units and model stated on this page. The formula area=d1*d2/2 · side=hypot(d1,d2)/2 · perimeter=4*side defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
