\r\n" );
document.write( "    Notice that the difference of dimensions of the pool is  16-12 = 4 meters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    If you surround the pool by the path of uniform width, the difference of dimensions of the larger rectangle will be the same 4 meters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    Now, you are given that the area of the larger rectangle is 480 square meters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    Hence, all you need to do is to find the decomposition of the number 480 into the product of two numbers that differ in 4.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    What are these numbers ?   - But of course, 24 and 20.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    Then the width of the path is   =  4 ft.\r\n" );
