document.write( "Parallelogram:  Parallel Sides are Equal in Length
\n" );
document.write( "P = 2AD + 2AB = 100cm
\n" );
document.write( "Let x = AB, then AD = 2x + 5
\n" );
document.write( "Substitute:
\n" );
document.write( "2(2x+5) + 2x = 100cm
\n" );
document.write( "4x +10 + 2x = 100cm
\n" );
document.write( "6x = 90cm
\n" );
document.write( "x = 15cm  and (2x+5) = 35cm
\n" );
document.write( "2*30cm + 2*35cm = 100cm  Checks!
