Question

The side of a regular decagon is l Express the perimeter of the decagon using l

Answer 1

Answer:

10 l

Step-by-step explanation:

decagon has 10 sides so if the length of one side of the regular decagon is l then the perimeter should be 10 l this is because a regular decagon has all its sides equal

Answer 2

$\fontsize{14}{10}{\textup{\textbf{The required perimeter of the given regular decagon is 10l.}}}$

Step-by-step explanation:

A regular decagon is a polygon with 10 sides and the lengths of all the 10 sides are equal.

According to the given information, we have

length of a side of the regular decagon = l.

The PERIMETER of a polygon is equal to the sum of the lengths of all its sides.

Therefore, the PERIMETER of the given regular decagon is given by

$P=l+l+l+l+l+l+l+l+l+l=10l.$

Thus, the required perimeter of the given regular decagon is 10l.
