Answer:
9.6 km or 9600 m.
Step-by-step explanation:
The perimeter of a rectangular piece of land = 2(Length + Breadth)
= 2(0.7+0.5)
= 2(1.2)
= 2.4 km
\because1km\ =\ 1000m∵1km = 1000m
\therefore0.24\ =\ 1000\times0.24=2400∴0.24 = 1000×0.24=2400 m.
Since 4 rows of wire is required.
\therefore2400\times4=9600∴2400×4=9600 m.
\therefore9600\ m\ =\ 9.6\ km∴9600 m = 9.6 km
Therefore, length of wire required is 9.6 km or 9600 m.

Answer:
9.6km

Perimeter of the rectangular piece of land
= 2(0.7km+0.5)
= 1.4km+1km
=2.4km
2.4km is the perimeter now we have to multiply it with four
2.4km*4= 9.6km
