Given that the length of the rectangular piece of land = 0.5km.
Given that the width of the rectangular land = 0.3 km.
We know that perimeter of a rectangle is given by = 2(l+b)
= 2(0.5 + 0.3)
= 2(0.8)
= 1.6.
Given that Each side to be fenced with 3 rows of wires.
Therefore the total length of wire needed = 1.6 * 3
= 4.8 km.
Hope this helps!
