Hey mate Here is your answer
The Rectangular field's dimensions are 90km and 70km
So To find the complete round we have to find the perimeter
Perimeter of a Rectangle: 2( l + b)
2 ( 90 + 70)
2 × 160
320km
Now the person walks 4km per hour hence the taken by him will be
320/4 = 80 Hours
Answer : The person will take 80 hours
Hope it helps
