Length = L
\n" ); document.write( "Width = W\r
\n" ); document.write( "\n" ); document.write( "L+12 = 2W
\n" ); document.write( "L x W = 1040
\n" ); document.write( "(2W-12) x W = 1040
\n" ); document.write( "2W^2 -12W = 1040\r
\n" ); document.write( "\n" ); document.write( "W^2 - 6W = 520\r
\n" ); document.write( "\n" ); document.write( "(W-3)^2 - 9 = 520\r
\n" ); document.write( "\n" ); document.write( "W = 529^(1/2) + 3\r
\n" ); document.write( "\n" ); document.write( "W = 26\r
\n" ); document.write( "\n" ); document.write( "L = 40\r
\n" ); document.write( "\n" ); document.write( "
