Answer:
[tex]\text{1320m, Rs. 35640}[/tex]
Step-by-step explanation:
[tex]\text{Solution: }\\\text{Radius of circular pond}(r)=42\text{m}\\\text{So, perimeter of the pond}(P)=2\pi r=2\pi (42)=84\pi\approx264\text{m}[/tex]
[tex]\text{Now, length of wire required to fence it with 5 rounds = }5P=5\times264=1320\text{m}[/tex]
[tex]\text{Finally, cost of fencing = }1320\times27=\text{Rs }35640[/tex]
