l = 3x - 8
\n" ); document.write( "w = x
\n" ); document.write( "2(3x - 8) + 2x = 64.
\n" ); document.write( "6x -16 + 2x = 64
\n" ); document.write( "8x = 80
\n" ); document.write( "x = 10 ft the width.
\n" ); document.write( "The length = 3(10) - 8 = 22 ft.
\n" ); document.write( "2(22) + 2(10) = 64 feet. This does check.
