Question

the side of a square lawn is 130 m what is the length of the wire required for the fencing it two time

Answer 1

Answer :

The length of the wire required to fence it twice is equal to 1040 m.

Step-by-step explanation :

Given,

Side of square, $a=130$ m

To find - Length of wire required to fence it twice.

In order to find the length of wire required to fence it twice, we need to take out the perimeter of the square and double it.

Perimeter of square -

⇒ $4\times a$

⇒ $4\times 130$

⇒ $520$ m

Length of wire required to fence it twice -

⇒ $Perimeter\times 2$

⇒ $520\times 2$

⇒ $1040$ m

Answer 2

Answer -

Side of square = 130 m

Length of wire required to fence it twice = 2 × perimeter

==> 2 (4 × side)

==> 2 (4 × 130)

==> 1040 m
