Let L represent the length.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The breadth is then L - 4.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The perimeter is equal to twice the length, plus twice the breadth:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2L + 2(L - 4) = 68\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2L + 2L - 8 = 68\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4L - 8 = 68\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4L = 76\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "L = 19\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then, the breadth is L - 4 = 19 - 4 = 15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solution: Length = 19, Breadth = 15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check: 19 + 15 + 19 + 15 = 68\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
