Which prefix means AROUND and is used in the word perimeter?

Explanation:
Peri- is the prefix that means around. In perimeter, peri- combines with meter (measure) to describe the measurement around a shape—the distance around its outside. This same prefix shows up in many medical terms that mean “around” or “surrounding,” like pericardium (around the heart) or perinatal (around birth). Note that circum- also means around, but it’s used in words like circumference, not perimeter. INTER- and SUPRA- do not convey the idea of around.
