W=width; L=length=2W+10ft; P=perimeter=2(L+W)=92 ft
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "92 ft=2(L+W) Divide each side by 2.
\n" ); document.write( "46 ft=L+W Substitute for L.
\n" ); document.write( "46 ft=(2W+10 ft)+W Subtact 10 ft from each side.
\n" ); document.write( "36 ft=3W Divide each side by 3.
\n" ); document.write( "12 ft=W ANSWER: The width is 12 feet.
\n" ); document.write( "L=2W+10ft=2(12ft)+10ft=34ft ANSWER 2: The length is 34 feet.
\n" ); document.write( "CHECK:
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "92 ft=2(34 ft+12 ft)
\n" ); document.write( "92 ft=2(46 ft)
\n" ); document.write( "92 ft=92 ft
\n" ); document.write( "
\n" ); document.write( "
\n" );
