Solution :
The area of the square field = 4 hectare \[=4\times 10000=40000\,\,{{\text{m}}^{2}}\] Side of field \[=\sqrt{40000}=200\,\,\text{m}\] \[\therefore \]It perimeter \[=200\times 4=800\,\,\text{m}\] \[\therefore \]Time taken to run around \[=\frac{800}{6\times 1000}=\frac{8}{60}\text{h}=8\,\,\min \]You need to login to perform this action.
