The answer would be $\sqrt{61}$ $sqrt61$ 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:-
$h^{2} = p^{2} + b^{2}$ $h^2=p^2+b^2$

Substituting the values:-

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