\n" ); document.write( "200 meters will be the perimeter; let L=length=60m; w=width:
\n" ); document.write( ".
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "200m=2(L+W) Divide each side by 2
\n" ); document.write( "100m=L+W Put in value for L.
\n" ); document.write( "100m=60m+W
\n" ); document.write( "40m=W
\n" ); document.write( "The length is 60m and the width is 40m, so:
\n" ); document.write( ".
\n" ); document.write( "Area=LW=(60m)(40m)=2400 m^2
\n" ); document.write( "
\n" );
