If the perimeter of a regular enneagon is 74.7mm how long is one side?

8.3 mm

Step-by-step explanation:

An enneagon is a polygon with 9 sides, also called nonagon.

In a regular polygon, all sides are congruent, so the length of any side is the perimeter divided by the number of sides.

length of a side = perimeter/number of sides

length of a side = 74.7 mm/9 = 8.3 mm

(3x-8) or (3x+8)
