Answer:Total perimeter = 2(l+b)
= 2(0.7 + 0.5)
= 2*1.2= 2.4 km
Since 4 rows is fenced at each side,
Total length of the wire needed
= 4*2.4= 9.6 km

Answer:
Given length of rectangle field = 0.7 km
breadth of rectangle field = 0.5 km
Perimeter of rectangle field = 2[l+b]
=2[0.7+0.5]
Perimeter of field = 1.2×2=2.4km
length of filed fencing = 4P=4×2.4
length of fence = 9.6km
∴ length of wire needed is 9.6 km.
