Question

Find the perimeter of a polygon having 'n' sides where the length of each side is 'a' units.

• A. $(n+1)aunits$
• B. $(n-1)aunits$
• C. $\frac{\left(na\right)}{2}units$
• D. $naunits$

Answer 1

The correct option is D

$naunits$

A regular polygon has all sides equal in length. Therefore, if such a polygon has 'n' sides and length of each side is 'a' units, its
perimeter $=a+a+a+a...$ (n times)
$=na$ units
