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
\therefore0.24\ =\ 1000\times0.24=2400 m.
Since 4 rows of wire is required.
\therefore2400\times4=9600 m.
\therefore9600\ m\ =\ 9.6\ km
Therefore, length of wire required is 9.6 km or 9600 m.
