\n" ); document.write( "I don't know what x is, but:
\n" ); document.write( ".
\n" ); document.write( "W=width; L=length=W+25m; P=perimeter=134m
\n" ); document.write( ".
\n" ); document.write( "P=2(L+W) Put in value for P
\n" ); document.write( "134m=2(L+W) Divide each side by 2.
\n" ); document.write( "67m=L+W Substitute for L.
\n" ); document.write( "67m=(W+25m)+W Subtract 25m from each side.
\n" ); document.write( "42m=2W Divide each side by 2.
\n" ); document.write( "21m=W
\n" ); document.write( "ANSWER 1: The width is 21 meters.
\n" ); document.write( ".
\n" ); document.write( "L=W+25m=21m+25m=46m
\n" ); document.write( "ANSWER 2: The length is 46 meters.
\n" ); document.write( ".
\n" ); document.write( "CHECK:
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "134m=2(46m+21m)
\n" ); document.write( "134m=2(67m)
\n" ); document.write( "134m=134m \n" ); document.write( "
\n" );
