A rectangular piece of land measures 0.7 km by 0.5 km. Each side is to be fenced with 4 rows of wires. What is the length of the wire needed?
Answer
Given:
Length of the land = 0.7 km
Breadth of the land = 0.5 km
Perimeter of rectangular land = 2(length + breadth)
= 2(0.7 + 0.5) km
= 2 × 1.2 km
= 2.4 km
Since each side is to be fenced with 4 rows of wires,
Length of the wire needed = 4 × Perimeter
= 4 × 2.4 km
= 9.6 km
Hence, the length of the wire needed is 9.6 km.
