Description
Use (baseWidth + topWidth) × height / 2 for sectionArea and multiply by length for envelopeVolume.
Simple site geometry approximates an area, section, or volume using ideal shapes. Coherent length units and the distinction between signed and unsigned quantities determine the result's meaning.
Use (baseWidth + topWidth) × height / 2 for sectionArea and multiply by length for envelopeVolume.
When to use this tool
Use Hedge Trapezoid Canopy Area Term when you need one transparent landscape geometry component.
How to use the tool and how it works
- Enter baseWidth, topWidth, height, length. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read sectionArea, envelopeVolume. Use the output convention below.
Use (baseWidth + topWidth) × height / 2 for sectionArea and multiply by length for envelopeVolume.1

| topWidth | Top Width | Required. Finite number; minimum 0. |
| height | Height | Required. Finite number; minimum 0. |
| length | Length, count, or code length under the stated domain and unit convention. | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| sectionArea | Section Area | Required. Finite number. |
| envelopeVolume | Envelope Volume | Required. Finite number. |

}Limitations and assumptions
- This is a constant trapezoidal envelope, not actual leaf volume, biomass, or pruning guidance.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use a surveyed terrain or construction model when irregular shapes, settlement, drainage, and structural performance matter.
