Solution:-
Hypotenuse (x) of the right triangle = [tex] \sqrt{7² \: + \: 11²} [/tex]
Hypotenuse (x) of the right triangle = [tex] \sqrt{49 \: + \: 121} [/tex]
Hypotenuse (x) of the right triangle = [tex] \sqrt{170} [/tex]
Hypotenuse (x) of the right triangle = 13
The hypotenuse (x) of the right triangle is 13 m.
Hence, option (D) 13 m is correct. [Answer]
