To do that, we would need to know what is "described above".
To calculate that, we'd need to know the coefficient of static friction between the block and the surface, which you haven't told us.
Distance covered is given as follows
1). 7 km North
2). 5 km North
3). 1 km East
Now total distance covered will be given as
Now in order to find the displacement we will show all with their directions
towards North
towards East
So total displacement is
so net displacement will be
so displacement is 12.04 km
