Question

a square has an area of 9 cm squared. Whats is its side length?

Answer 1

Given: The area of the square is $9$cm squared.

We have to find the length of the side of the square.

As we know that the area of the square is calculated by$side^{2}$.

$\therefore$The area of square=$side^{2}$

We are solving in the following way:

Let assume the side of the square will be$x.$

We have,

The area of the square is $9$cm squared.

Now,

=> The area of square=$side^{2}$

$=>9=x^{2} \\=>x=\sqrt{9}\\=>x=3$

We get, $x=3$cm.

Hence, the length of the side of the square will be $3$cm.

Answer 2

As per the data given in the question,

We have to determine the side of the square.

As we know that,

Square is a quadrilateral in which the measurement of all the sides are equal.

So, from given data,

We have,

The area of the square $9\:cm^2$

As we have to determine the length of the side of the square.

As we know that,

$Area\: of\: square\:= side^{2}.$

So, Let assume the side of the square be x cm.

So,

$=>9=x^{2} \\=>x=\sqrt{9}\\=>x=3$

Hence, the length of the side of the square will be 3 cm.
