\r\n" );
document.write( "Perimeter = sum of 3 sides = 39\r\n" );
document.write( "i.e. 7 + 16 + x = 39\r\n" );
document.write( "x + 23 = 39 -> this is the equation you are looking for.\r\n" );
document.write( "Solve for x\r\n" );
document.write( "x = 39 - 23 = 16\r\n" );
document.write( "As simple as that :)\r\n" );
