Solution
The correct option is B 560 m
Total length of wire required to fence the field = Perimeter of the triangular field = Sum of the length of the 3 sides
Hence, total length of wire required to fence the field = 220 m + 160 m + 180 m = 560 m.
Total length of wire required to fence the field = Perimeter of the triangular field = Sum of the length of the 3 sides
Hence, total length of wire required to fence the field = 220 m + 160 m + 180 m = 560 m.
