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 ?

Options

A. 43 m
B. 4 m
C. 3m
D. 5 m

Explanation

`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`
