\n" ); document.write( "\n" ); document.write( "A regular pentagon has a side length of 8 inches.
\n" ); document.write( "perimeter of the pentagon is
\n" ); document.write( "\"P=5%2A8in\"
\n" ); document.write( "\"P=40in\"
\n" ); document.write( "
\n" ); document.write( "if a square has the same perimeter as the pentagon, than \"P=4a\"=>\"4a=40in\"=>\"a=10in\"\r
\n" ); document.write( "\n" ); document.write( "so, the area of the square will be: \r
\n" ); document.write( "\n" ); document.write( "\"A=a%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"A=%2810in%29%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"A=100in%5E2\"\r
