width = x
\n" ); document.write( "length = 3.5 x\r
\n" ); document.write( "\n" ); document.write( "Area = 12 m^2\r
\n" ); document.write( "\n" ); document.write( "Area = L*W\r
\n" ); document.write( "\n" ); document.write( "12=x*3.5x
\n" ); document.write( "12=3.5x^2
\n" ); document.write( "3.4285=x^2
\n" ); document.write( "x= 1.85\r
\n" ); document.write( "\n" ); document.write( "width 1.85
\n" ); document.write( "length = 3x = 6.47
\n" ); document.write( "
