The answer would be #sqrt61# feet.

Explanation:

Imagine an right angle triangle with perpendicular(p) as the post , the ground as the base(b) and the required length be the hypotenuse(h).

Given:-
b=5 feet
h=6 feet

By Pythagoras theorem:-
#h^2=p^2+b^2#

Substituting the values:-

#h^2=5^2+6^2#
or
h=#sqrt(25+36)#
therefore hypotenuse(h)=#sqrt 61# feet which is also the required value.
