P=perimeter=110m; W=width=21m; L=length
\n" ); document.write( "P=2(L+W) Divide each side by 2.
\n" ); document.write( "P/2=L+W Subtract W from each side.
\n" ); document.write( "P/2-W=L Plug in numbers.
\n" ); document.write( "110m/2-21m=L
\n" ); document.write( "55m-21m=L
\n" ); document.write( "34m=L ANSWER: The length is 34 meters.
