A=area L=length W=width
\n" ); document.write( "A=L*W
\n" ); document.write( "L=2W
\n" ); document.write( "substitute 2W for L: A=W*2W
\n" ); document.write( "W*2W=800
\n" ); document.write( "2W^2=800
\n" ); document.write( "divide both by 2: W^2=400
\n" ); document.write( "square root of both: W=20 feet
\n" ); document.write( "L=40 feet
\n" ); document.write( "Check:
\n" ); document.write( "20*40=800 square feet
