Answer:
17.2 meters
Step-by-step explanation:
This is a right triangle problem
a^2 + b^2 = c^2
The 1st triangle:
a^2 + 10.1^2 = 12.2^2
a^2 = 12.2^2 - 10.1^2
a^2 = 46.83
a = 6.8432448444
The 2nd triangle
a^2 + 6.4^2 = 12.2^2
a^2 = 12.2^2 - 6.4^2
a^2 = 107.88
a = 10.3865297381
---------------------------------
Width = 6.8432448444 + 10.3865297381
Width = 17.2297745825
Width ≈ 17.2 meters
