Answer:
So, the distance covered by man if he takes 3 rounds is 3491.16 inches
Explanation:
We are given area of square field i.e 84642 and we need to find distance covered by man if he takes 3 rounds of the field.
Distance covered by man = Perimeter of square field
First we have to find length of side of square field.
The formula used is Area of square= (Length)^2
Putting value of area and finding length.

So, length of square field is 290.93 inches
Now finding the distance covered by man if he takes 3 rounds
First find perimeter
Perimeter of square = 4*length
Perimeter of square = 4*290.93
Perimeter of square = 1163.72 inches
Distance covered by man if he takes 3 rounds = 3*Perimeter of square
Distance covered by man if he takes 3 rounds = 3*1163.72
So, the distance covered by man if he takes 3 rounds is 3491.16 inches
