Question 429042
Solution:The central angle of pentagon is 360/5=72 degrees.The area of pentagon is given by the formula:

{{{A=(1/2)*(p*a)}}}, where p=50 inches, is the perimeter of pentagon and a is the

line segment perpendicular from center to the base: {{{a=5/tan(36)}}}, and area:

{{{A=((1/2)*50)/(tan(36))}}}

A=39.4 square inches.

Done.
