If the 70-foot long wall of the building is one side of the rectangular playground
\n" ); document.write( "and the adjacent sides are $\"x\"$ feet long, we need
\n" ); document.write( " $\"x%2B70%2Bx\"$ feet of fencing.
\n" ); document.write( "
\n" ); document.write( "Our equation is
\n" ); document.write( " $\"x%2B70%2Bx=340\"$
\n" ); document.write( " $\"2x%2B70=340\"$
\n" ); document.write( " $\"2x=340-70\"$
\n" ); document.write( " $\"2x=270\"$
\n" ); document.write( " $\"x=270%2F2\"$
\n" ); document.write( " $\"highlight%28x=135%29\"$
\n" ); document.write( "The playground will be $\"highlight%28135%29\"$ feet long. \n" ); document.write( "

\n" );
