Central angle of a polygon=10 degrees
---
--> 360/10 = 36 sides.
-----
Perimeter= 108 cm
108/36 = 3 = side length.
=====
What is the area
Area = where n + # of sides, s = side length

Just calculator work now.

.
I will assume that the polygon is a REGULAR polygon.

The number of sides is  = 36.


The side length is  = 3 cm.


The apothem "a" is   =  = tan(5°),  or  a = .


Then the area =  =  = 54*tan(5°) .


I leave it to you to calculate the number.
