W=breadth; L=length=2W P=perimeter=2(L+W)=72m
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "72m=2(L+W) Divide each side by 2
\n" ); document.write( "36m=L+W Substitute for L
\n" ); document.write( "36m=2W+W
\n" ); document.write( "36m=3W Divide each side by 3.
\n" ); document.write( "12m=W ANSWER 1: The breadth is 12 meters.
\n" ); document.write( "L=2W=2(12m)=24m ANSWER 2: The length is 24 meters.
\n" ); document.write( "CHECK:
\n" ); document.write( "P=2(L+W)
\n" ); document.write( "72m=2(24m+12m)
\n" ); document.write( "72m=2(36m)
\n" ); document.write( "72m=72m
\n" ); document.write( "
\n" ); document.write( "
\n" );
