Here area= cost/rate
\n" ); document.write( "so,
\n" ); document.write( ".
\n" ); document.write( " $\"area=+12000%2F10+=+1200+yd%5E2+\"$
\n" ); document.write( "is the area.
\n" ); document.write( "perimeter is 140 yards.
\n" ); document.write( "so, 2(l+b) = 140
\n" ); document.write( "l+b= 70
\n" ); document.write( "b= 70- l ----(1)
\n" ); document.write( ".
\n" ); document.write( "area = l*b =l*(70-l)=1200
\n" ); document.write( "solve this, we will get l=40 yd or 30 yd.
\n" ); document.write( "when l= 40yd, b= 30yd
\n" ); document.write( "and when l=30yd , b= 40 yd.
\n" ); document.write( ".
\n" ); document.write( "so, dimensions are 40yd x 30 yd. \n" ); document.write( "

\n" );
