Question

A square piece of land has each side equal to 100 m. If 3 layers of metal wire
have to be used to fence it, what is the length of the wire?​

Answer 1

LENGTH OF THE WIRE = PERIMETER OF THE FIELD×3

= 4×100 × 3

= 1200m

Answer 2

$\huge \underline \mathbb {SOLUTION:-}$

AnswEr:

• The length of wire required to fence three layers = 1200 m

Given Information:

• Side of the square field = 100 m

Need To Find:

• Wire required to fence the square filed = ?

ExPlanation:

Side of the square field = 100 m [Given]

Formula used here

• Perimeter of the square = 4 × Side

Putting the values according to the given formula:

Perimeter of the square field = 4 × 100

Perimeter of the square field = 400 m

• Hence, the perimeter of the square field is 400m.

This perimeter is the length of wire required to fence one layer.

Therefore:

• The length of wire required to fence three layers = 3 × 400 m = 1200 m

What is Perimeter?

The length of the boundary of a closed figure is called the perimeter.

Perimeter of rectangle = 2 × (Length + Breadth)

Perimeter of a square = 4 × Side
