# Consider regular pentagon ABCDE of Exercise 44. In terms of radius length r, find an expression for the area of ABCDE.

To determine

To find:

An expression for the perimeter of ABCDE if regular pentagon ABCDE, each radius has length r.

Explanation

Consider the following figure,

The area of polygon is

A=r2nsin(360n)2

Where r is the radius and n is number of sides.

Consider for pentagon givne that radius = r and n=5.

Substitute the avlue of r and n in the above area equaiton to get the following,

A=r2(5)sin(3605)2=<
