Perimeter = 40 feet
\n" ); document.write( "Length 1 ( 2 x -7 )
\n" ); document.write( "Width = x ft
\n" ); document.write( "Perimeter =2(L+W)
\n" ); document.write( "Perimeter = 2(((2x-7)+x)
\n" ); document.write( "Perimeter = 2((2x-7 +x)
\n" ); document.write( "Perimeter =4x-14+2x
\n" ); document.write( "40 =6x-14
\n" ); document.write( "40 -=6x
\n" ); document.write( "40+14=6 x
\n" ); document.write( "54=6x
\n" ); document.write( "x=9 ft Width
\n" ); document.write( "Length =11ft
\n" ); document.write( "
\n" );
