\n" );
document.write( "A pasture is bounded by a river on one side. 
\n" );
document.write( "The farmer has 600 yards for enclosing a rectangular area of 40,000 square yards.
\n" );
document.write( "Let x represent the length opposite the river
\n" );
document.write( "  x*w = 40,000
\n" );
document.write( "    w = 40,000/x
\n" );
document.write( " 2(40,000/x) + x = 600
\n" );
document.write( "   80,000 + x^2 = 600x
\n" );
document.write( " x^2 -600x + 80,000 = 0
\n" );
document.write( " (x - 200)(x- 400)= 0
\n" );
document.write( "I.  (x- 100)= 0  x = 100, the length and 250 are the widths (fence = 600)
\n" );
document.write( "II. (x- 400)= 0  x = 400, the length and 100 are the widths (fence = 600) \n" );

\n" );
