Answer:
Explanation:
A=1/2 a p a is apothem; p is perimeter of base
p=22*5 =110
a you need to find by making a triangle with the radius and finding the angle of the right triangle
All external angles of any polygon =360
divide by 5 and then 2 to find triangle
=54
Use tan 54 = a/11
a=15.14
A= 1/2 *15.14 *54
408.8
