Question

in following figure 1 a person move from 'A' through B,C,D,E upto F, calculate distance between Aand f

Answer 1

Line which you draw from A to F then AFG is forming a right triangle where we have to take out distance of AF or hypotenuse of triangle.
H^2=B^2+P^2
H^2=10^2+5^2
H^2=100+25
H^2=125 , H=_/125=11.15 or 11.2
