Question

Which of the following is true for the perimeter of a regular pentagon?

• A. It is three times the length of one of its sides.
• B. It is four times the length of one of its sides.
• C. It is five times the length of one of its sides.
• D. It is six times the length of one of its sides.

Answer 1

The correct option is C It is five times the length of one of its sides.

Pentagon is a five-sided closed polygon.
A regular pentagon has all of its sides equal.
We know, perimeter of a regular polygon = (number of sides)×(side-length)
So, perimeter of a regular pentagon= 5×(side-length)
