Answer:
So, the distance covered by man if he takes 3 rounds is 3491.16 inches
Step-by-step 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.
![Area of square= (Length)^2\\\sqrt{Length} =\sqrt{84642} \\Length= 290.93\\](https://tex.z-dn.net/?f=Area%20of%20square%3D%20%28Length%29%5E2%5C%5C%5Csqrt%7BLength%7D%20%3D%5Csqrt%7B84642%7D%20%5C%5CLength%3D%20290.93%5C%5C)
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
