In this problem
AB=DC
BC=AD
see the attached figure with letters to better understand the problem
we have that
the formula to calculate the distance between two points is equal to
we have the points
<em>Find out the distance BC</em>
we have
substitute in the formula
<em>Find out the distance AB</em>
we have
substitute in the formula
<em>Find out the area</em>
we have
substitute
C:x, in the bottom equation
We know that
The sum of exterior angles of any polygon is 360 degrees.
Each exterior angle of a regular polygon = 360/n
where n is the number of sides.
<span>So
n = 360/20 = 18
</span>
the answer is the option
<span>b.18 </span>
