Area of farm = 750 sq. m\r
\n" ); document.write( "\n" ); document.write( "110 meters will be the perimeter\r
\n" ); document.write( "\n" ); document.write( "let one side be x\r
\n" ); document.write( "\n" ); document.write( "the other side will be 110-2x /2\r
\n" ); document.write( "\n" ); document.write( "Area = L * W\r
\n" ); document.write( "\n" ); document.write( "x((110-2x /2)=750\r
\n" ); document.write( "\n" ); document.write( "x(110-2x /2 ) =750\r
\n" ); document.write( "\n" ); document.write( "110x-2x^2/ 2 =750\r
\n" ); document.write( "\n" ); document.write( "110x-2x^2= 1500\r
\n" ); document.write( "\n" ); document.write( "2x^2-110x+1500=0\r
\n" ); document.write( "\n" ); document.write( "x^2-55x+750=0\r
\n" ); document.write( "\n" ); document.write( "x^2-30x-25x+750=0\r
\n" ); document.write( "\n" ); document.write( "x(x-30)-25(x-30)=0\r
\n" ); document.write( "\n" ); document.write( "(x-30)(X-25)=0\r
\n" ); document.write( "\n" ); document.write( "x= 30 OR 25\r
\n" ); document.write( "\n" ); document.write( "The dimensions of the farm are 35 by 25 meters\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
