Morphology

perimeter = meter (semi-transparent) = peri + meter

The parts are recognizable as 'peri-' meaning around and 'meter' meaning measure, but the noun has specialized to mean the boundary measured around rather than a straightforward compositional phrase.

Etymology

Perimeter comes from Greek parts peri- 'around' and metron 'measure'. So, it means the distance measured 'around' the outer edge of a shape or place, which is why we add all the sides to find a perimeter.
