The perimeter of a regular hexagon is 138 cm. How long is each side?

Correct option is B

Given:
The perimeter of the regular hexagon = 138 cm
A regular hexagon has 6 equal sides.
Formula Used:
The perimeter of a regular hexagon is the sum of the lengths of all its sides.
Perimeter = 6 × Side length
Solution:
Let the side length be S.
138 = 6 × S
S = $$\frac{138} 6$$​= 23 cm
Each side of the hexagon is 23 cm.
