Question

the length of the a wire is 12 cm long a square is formed by folding it . what will be the area of the square ​

Answer 1

Answer:

Therefore the area of the square is $9\;cm^{2} .$

Step-by-step explanation:

As per the data provided in the given question.

The given data is as follows,

The length of the a wire is 12 cm long and square is formed by folding it.

We have to find the area of the square (A).

At first we will find the side of a square i.e. (a).

The square is formed by folding 12 cm long wire.

A square has 4 sides so we will divide the length of wire i.e. 12 cm by 4.$a=\frac{12}{4}$

We will divide above value by 2

We get,

$a=\frac{6}{2}$

Again we will divide above value by 2

$a=3\;cm$

A side of a square (a) is 3 cm.

Now we will find the area of the square (A).

Here we will using the formula of area of the square.

$A=a^{2}$

Now we will substitute the value of a in above formula.

$A=3^{2}$

3 square we will write as below,

[tex]A=3\times3\\ A=9\;cm^{2} [/tex]

Therefore the area of the square is $9\;cm^{2} .$
