Call the width of the field w (for width)
\n" ); document.write( "The length is twice the width, so the length is 2w\r
\n" ); document.write( "\n" ); document.write( "The area of the field is the length times the width = 2w X w = \"2w%5E2\"\r
\n" ); document.write( "\n" ); document.write( "So \"2w%5E2\" = 28900\r
\n" ); document.write( "\n" ); document.write( "Divide both sides by 2\r
\n" ); document.write( "\n" ); document.write( "\"w%5E2\" = 14450\r
\n" ); document.write( "\n" ); document.write( "Take the square root of both sides :\r
\n" ); document.write( "\n" ); document.write( "The width is 120.21 and the length is 240.42
\n" ); document.write( " \n" ); document.write( "
\n" );
