document.write( "The diagonals of a rectangle have equal lengths. Since AC has a length of 28,\r\n" );
document.write( "and AC is a diagonal, the other diagonal BD also has a length of 28.\r\n" );
document.write( "\r\n" );
document.write( "The diagonals of a rectangle also bisect each other.  So diagonal BD is\r\n" );
document.write( "bisected by the other diagonal AC at point E.  And since diagonal BD has\r\n" );
document.write( "a length of 28 then BE and ED both have a length which is  of 28,\r\n" );
document.write( "or 14 each.\r\n" );
