I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
 SEE ATTACHED IMAGE. 
 First we look for the hypotenuse of both triangles.
 Left triangle:
 Sine (68.1) = (1.75) / (h)
 h = (1.75) / Sine (68.1)
 h = 1.886108667
 h = 1.9m
 Right triangle:
 Sine (49.4) = (1.75) / (h)
 h = (1.75) / Sine (49.4)
 h = 2.304841475
 h = 2.3m
 Finally adding the perimeter:
 P = 5 + 1.9 + 2.75 + 2.3
 P = 11.95 m
 Answer: 
 she will need to build 11.95 m of fence
