Answer:

She is 5 km from his initial position and in SOUTH EAST direction.

Step-by-step explanation:

Refer the attached figure

A lady walks 8 km towards east i.e. AB = 8 km

Then She walks 3 km towards south i.e. BC = 3 km

Then She walks 4 km towards west i.e. CD =4 km

Now we are supposed to find how far is she from his initial position i.e.AD

ED = BC = 3 km

EB = DC = 4 km

AB - EB = AE

8 km - 4 km = AE

4 km = AE

In ΔAED

Hypotenuse^2=Perpendicular^2+Base^2

AD^2=AE^2+ED^2

AD^2=4^2+3^2

AD^2=16+9

AD^2=25

AD=\sqrt{25}

AD=5

Hence she is 5 km from his initial position and in SOUTH EAST direction.
