document.write( "Let W be the width, in meters.\r\n" );
document.write( "Then the length L = 5W, according to the condition.\r\n" );
document.write( "\r\n" );
document.write( "From the condition, you have this equation for the area\r\n" );
document.write( "\r\n" );
document.write( "L*W = 10580,   or\r\n" );

document.write( "W =  = 46 m.\r\n" );
document.write( "\r\n" );
document.write( "Hence, L = 5*46 = 230 m.\r\n" );
document.write( "\r\n" );
document.write( "Now the perimeter is P = 2*230 + 2*46 = 552 m.\r\n" );
