Check

Rounding an intermediate value too early when the output feeds another step.
Using the right formula with the wrong measurement label or axis.

Example

Side Length 6 gives Perimeter 66. 00.

Formula

perimeter = 11 x side

A regular hendecagon has 11 equal sides, so the perimeter is a clean repeated-length calculation.

This is the outside boundary only, not the area.
