Let {{{ x }}} ft = the length of the shortest piece
One of the 2 remaining  pieces is {{{ 2x }}} ft
The 3rd piece is {{{ x + 5 }}} ft 
---------------------------------------------
given:
{{{ x + 2x + x + 5 = 33 }}}
{{{ 4x + 5 = 33 }}}
{{{ 4x = 28 }}}
{{{ x = 7 }}}
and
{{{ 2x = 14 }}}
and
{{{ x + 5 = 12 }}}
--------------------
The lengths are:
7 ft
14 ft
