Given:
The length of the side in a pentagon is s = 4ft.
To find:
The area of the pentagon and apothem.
Explanation:
The formula for the area of the regular pentagon is,
[tex]\begin{gathered} A=5\times\frac{\sqrt{3}}{4}s^2 \\ A=5\times\frac{\sqrt{3}}{4}\times4^2 \\ A=20\sqrt{3}ft^2 \end{gathered}[/tex]The area of the regular pentagon using apothem is,
