Question

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 1

Length of the Land (l) = 0.7 km

Breadth of the land (b) = 0.5 km.

perimeter of the land = 2 × (l + b)

= 2 × (0.7 + 0.5)

= 2 × (1.2)

= 2.4 km.

The length of the wire required to fenced the land is given by 4 × 2.4 = 9.6 km.
