P>78
\n" ); document.write( "L=17
\n" ); document.write( "P=2L+2W
\n" ); document.write( " $\"78%3C2%2812%29%2B2W\"$
\n" ); document.write( " $\"78%3C24%2B2W\"$
\n" ); document.write( " $\"54%3C2W\"$
\n" ); document.write( " $\"27%3CW\"$
\n" ); document.write( "so the width has to be more than 27
\n" ); document.write( "i.e. 27.000000000000000000000000001 or 28, or 29, or 5001, or 9999994444444443333333322222222002134859784635385836238949 and so on
