Let x equal the width of the rectangle.
\n" ); document.write( "Let y equal the length of the rectangle.\r
\n" ); document.write( "\n" ); document.write( "The description of the problem leads to the equations\r
\n" ); document.write( "\n" ); document.write( "l=w+5 Equation #1)\r
\n" ); document.write( "\n" ); document.write( "2*l+2*w=66 in. Equation #2)\r
\n" ); document.write( "\n" ); document.write( "Substitute equation #1 into equation #2\r
\n" ); document.write( "\n" ); document.write( "2*(w+5)+2*w=66 in.\r
\n" ); document.write( "\n" ); document.write( "Solve the equation for w\r
\n" ); document.write( "\n" ); document.write( "2w+10+2w=66 in.\r
\n" ); document.write( "\n" ); document.write( "Collect like terms\r
\n" ); document.write( "\n" ); document.write( "2w+2w=66-10
\n" ); document.write( "4w+56\r
\n" ); document.write( "\n" ); document.write( "Solve for w\r
\n" ); document.write( "\n" ); document.write( "w=56/4 = 14\r
\n" ); document.write( "\n" ); document.write( "So, from equation #1) l=w+5=14+5=19\r
\n" ); document.write( "\n" ); document.write( "I hope that this helps. \n" ); document.write( "

\n" );
