Perimeter=2(L+W)=360 meters; L=3W+3
\n" ); document.write( "Substituting for L, solve for W:
\n" ); document.write( "2((3W+3)+W)=360 m
\n" ); document.write( "2(3W+3+W)=360 m
\n" ); document.write( "2(4W+3)=360 m
\n" ); document.write( "8W+6=360 m
\n" ); document.write( "8W=354 m
\n" ); document.write( " $\"W=354%2F8\"$ =44.25 m ANSWER 1 Width
\n" ); document.write( "L=3W+3=3(44.25 m)+3=135.75 m ANSWER 2 Length
\n" ); document.write( "CHECK:
\n" ); document.write( "Perimeter=2(L+W)=360 m
\n" ); document.write( "Perimeter=2(135.75 m + 44.25 m)=360 m
\n" ); document.write( "Perimeter=2(180 m)=360 m
\n" ); document.write( "Perimeter=360 m = 360 m
\n" ); document.write( " \n" ); document.write( "

\n" );
