Step-by-step explanation:

Here, pole is making a right triangle with the wall and pole is acting as hypotenuse. Thus by using Pythagoras theorem the length of pole can be calculated as:

[tex]length \: of \: pole = \sqrt{ {4}^{2} + {15}^{2} } \\ = \sqrt{16 + 225} \\ = \sqrt{241} ft \\ \red{ \boxed{\therefore \: length \: of \: pole =\sqrt{241} \: ft}}[/tex]

Hence, option B is the correct answer.
