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?

Given

Length of a piece of land = 0.7km

The breadth of a piece of land = 0.5km

Find out

We have to determine the length of the wire needed to fence the piece of land given

Solution

The length of the fence required is given by the perimeter of the rectangle

We know that

Perimeter of rectangle = 2 (Length + Breadth)

Perimeter of the plot = 2 (Length + Breadth)

= 2 (0.7 + 0.5)

= 2 (1.2)

= 2 × 1.2

= 2.4 km

Each side is to be fenced with 4 rows = 4 × 2.4

= 9.6 km

Answer

∴ Total length of the required wire is 9.6 km
