First, set up an equation to find the values for the length and width.\r
\n" ); document.write( "\n" ); document.write( "(x)* (2x) = 39200\r
\n" ); document.write( "\n" ); document.write( "2x^2 = 39000
\n" ); document.write( "x^2 = 19,600
\n" ); document.write( "x = 140.
\n" ); document.write( "The length is 280 yd.
\n" ); document.write( "The width is 140 yd.\r
\n" ); document.write( "\n" ); document.write( "So we need a length of 280 yards parallel to the river, and we need two sections of 140 for the width of the pasture.
\n" ); document.write( "Total, our farmer is going to need 560 square yards of fencing.
