Answer:
Types of polygon
Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon.
Regular and irregular polygons
Interior angles of polygons
To find the sum of interior angles in a polygon divide the polygon into triangles.
Irregular pentagons
The sum of interior angles in a triangle is 180°. To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°.
Example
Calculate the sum of interior angles in a pentagon.
A pentagon contains 3 triangles. The sum of the interior angles is:
180 * 3 = 540
The number of triangles in each polygon is two less than the number of sides.
The formula for calculating the sum of interior angles is:
(n - 2) * 180 (where n is the number of sides)

Answer:
The perimeter of the figure = 9.5 cm
Step-by-step explanation:
<em>Note: You probably missed to add the figure, but after a little research I found and am attaching the figure. I have answered your question based on the reference of that figure. But, I hope you would learn the concept so that you could solve any question based on this concept. So, please check the figure.</em>
<em>Solution:</em>
The perimeter of the figure is the sum of all the sides of the given figure as shown in the attached figure.
So, here is the formula to calculate the perimeter.
<em>Perimeter </em>=<em> AB + DE + BC + AE + BC </em>
As AE + DC = 1 1/5 cm, AB = 1 3/4 cm, DE = 1 1/4 cm, and BC = 1 3/10 cm
Therefore,
<em>Perimeter</em> = 1 3/4 + 1 1/4 + 13/10 + 1 1/5 ∵ AE + BC = 1 1/5
= (130 + 110 + 52 + 88) / 40
= 380/40
= 9.5 cm
So, the perimeter of the figure is = 9.5 cm
