document.write( "Let x be the shorter side dimension.\r\n" );
document.write( "Then the longer side length is 2x.\r\n" );
document.write( "\r\n" );
document.write( "The perimeter is x + 2x + x + 2x = 6x.\r\n" );
document.write( "\r\n" );
document.write( "It is 90 cm, so you have an equation \r\n" );
document.write( "\r\n" );
document.write( "6x = 90.\r\n" );

document.write( "Hence, x =  = 15 cm.\r\n" );
document.write( "\r\n" );
document.write( "Answer. The sides of parallelogram are 15 cm and 30 cm.\r\n" );
