“Omtrek,” which translates to “perimeter” or “circumference” in English, is indeed a five-letter word. Interestingly, the concept of perimeter has been around for millennia, with ancient civilizations like the Egyptians and Babylonians using it for practical purposes like land measurement and construction. Today, the calculation of perimeter remains a fundamental concept in geometry, applied in various fields like engineering, architecture, and even sports.
