Answer 1

The word perimeter means a path that surrounds an area. It comes from the Greek word 'peri,' meaning around, and 'metron,' which means measure. Its first recorded usage was during the 15th century. In mathematics, the perimeter refers to the total length of the sides or edges of a polygon, a two-dimensional figure with angles. When describing the measurement around a circle, we use the word circumference, which is simply the perimeter of a circle.
