Observe the figure:

\

The lengths of the sides of the pentagoan are \"\", \"\", \"\", \"\" and \"\".

\

Find the perimeter:

\

Perimeter of the pentagoan is \"\".

\

Substitute \"\", \"\", \"\", \"\" and \"\" in the formula.

\

\"\".

\

  \"\"                  (The common denominator is \"\")

\

   \"\"                                        (Combine like terms)

\

   \"\"                                      (Simplify)

\

Therefore, the perimeter of the pentagoan is \"\".

\

\

The perimeter of the pentagoan is \"\".
