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?
Solution:
Since the rectangular piece of land measuring 0.7 km by 0.5 km has to be fenced with 4 rows of wires on each side, the length of the wire required will be equal to four times the perimeter of the rectangular piece of land.
So, Length of the wire required = 4 x Perimeter of the rectangle = 4 x 2 (Length + Breadth)
Length = 0.7 km, Breadth = 0.5 km
Substituting the values we get,
⇒ 4 × 2 (0.7 + 0.5)
⇒ 4 × 2 × 1.2 = 9.6 km
Therefore, the length of the wire required to fence the park is 9.6 km.
