Point A is 11 m North of point B . Point C is 11 m East of point B. Point D is 6m North of point C. Point E is 7 m West of point D. Point F is 8 m North of point E. Point G is 4 m West of point F. How far is point F from point A ?

Answer»

43 m
4 m
3m
5 m

SOLUTION :
`AG=BG-AB=(CD+EF)-(AB)`
=(6+8)-11=3m
and GF=4 m
`AB=SQRT(AG^(2)+GF^(2))=sqrt(9+16)=5 m`
