Here we can see that after moving for distance of d = 3 m it takes turn at 60 degree angle
this will continue till it comes to its own position
so it will look like a polygon
here Number of sides of polygon is given as

now we will have

So here we have total sides are 6
So here it will be a polygon of 6 sides
so it's shape will be a regular hexagon of each side as 3m length
