document.write( "A. Determine the dimensions of the field?    \r\n" );
document.write( "\r\n" );
document.write( "   L + W = \"500%2F2\" = 250.   (1)\r\n" );
document.write( "   L*W   = 15400.         (2)\r\n" );

document.write( "   Express L = 250 - W from (1) and substitute into (2). You will get\r\n" );
document.write( "\r\n" );
document.write( "   (250-W)*W = 15400.\r\n" );

document.write( "   Simplify and solve this quadratic equation.\r\n" );
