How to use this tool
- Enter first side, second side.
- Select Calculate to view the result.
- Check the method and assumptions below before using the result.
Input reference and sample values
Use the units and choices shown for each field. Sample values are provided for practice, not as recommendations.
| Input | Format and units | Sample |
|---|---|---|
| First side | Numeric value. Unit: m. Must be greater than zero. | 8 |
| Second side | Numeric value. Unit: m. Must be greater than zero. | 5 |
Result for these sample inputs
26 m
Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.
The method, explained
Perimeter = 2 × (first side + second side).
Using first side = 8 m, second side = 5 m, the result is 26 m. Change these example inputs to match your task; use the method above to check each step.
What to keep in mind
Use the indicated units consistently. Ideal shapes are assumed; dimensions must describe the same object. Display rounding does not increase measurement precision.
