Area = Length * Width
\n" ); document.write( ".
\n" ); document.write( "L = 2-x
\n" ); document.write( ".
\n" ); document.write( "W = 4*x
\n" ); document.write( ".
\n" ); document.write( "A = (2-x)(4x)
\n" ); document.write( ".
\n" ); document.write( "A graph of the area can help you find the maximum.
