area of a rectangle is length * width
\n" ); document.write( "width = w
\n" ); document.write( "length = 1.6 * w
\n" ); document.write( "length * width = 1.6*w*w = 1.6*w^2.
\n" ); document.write( "1.6*w^2 = 9000
\n" ); document.write( "w^2 = 9000 / 1.6 = 5625
\n" ); document.write( "w = (5625)^(1/2) = 75
\n" ); document.write( "width = 75
\n" ); document.write( "length = 1.6 * 75 = 120.
\n" ); document.write( "calculating area = length * width = 75 * 120 = 9000.
\n" ); document.write( " \n" ); document.write( "
