document.write( "Hi,
\n" );
document.write( "Let x be the width.  Then length is 4x
\n" );
document.write( "twice the length + twice the width = P
\n" );
document.write( "2*4x  + 2x = 90cm
\n" );
document.write( "10x = 90cm 
\n" );
document.write( "x = 9cm
\n" );
document.write( "width is 9cm and the length is 36cm\r
\n" );
document.write( "\n" );
document.write( "checking our answer
\n" );
document.write( "72 + 18 = 90 \n" );
document.write( "
