Perimeter is:
\n" ); document.write( "L+L+W+W
\n" ); document.write( "or
\n" ); document.write( "2L+2W
\n" ); document.write( "or
\n" ); document.write( "2(L+W)
\n" ); document.write( ".
\n" ); document.write( "Since the problem fixed L as 15 cm AND the perimeter as greater than 76 we get our equation:
\n" ); document.write( "2(15+W) > 76
\n" ); document.write( "30 + 2W > 76
\n" ); document.write( "2W > 46
\n" ); document.write( "W > 23 cm
\n" ); document.write( "
\n" ); document.write( "
\n" );
