\n" );
document.write( "parallelogram with sides that are 10cm and 20cm long
\n" );
document.write( " sin 30° = h/10cm
\n" );
document.write( " 10cm* sin 30° = h
\n" );
document.write( "          5cm = h
\n" );
document.write( "Area is base*height
\n" );
document.write( " a = 5cm* 20cm = 100cm^2 \n" );
document.write( "

\n" );
