Question

Find the area of square made from 120m long wire.​

Answer 1

Answer:

area of square is 14400m sq.

Answer 2

Given,

The length of the wire is $120m.$

To find,

The area of the square made from wire =?

Solution,

We are given,

The length of wire = Perimeter of square = $120 m.$

We know,

The perimeter of the square = $4\times a$  where $a$ is the side of the square.

Now putting the value in the formula we get the side of the square as,

⇒ $120=4\times a$

⇒ $a=30$

Now,

The area of the square is given as $a^2$

So the area of a square with side  $a=30m$ is,

Area = $30\times 30 m^2$

Area = $900 m^2$

Hence, the area of the square made from 120 m long wire is 900 m^2
