Question

the area of square is 400cm. find the side of square?​

Answer 1

Question :-

The area of square is 400cm. find the side of square?

Given :-

• Area of a square = 400cm²

To find :-

Side of square.

Formula used :-

Area of square = side²

Solution :-

Area of a square = 400cm²

Side of square = ?

$\implies\bf side^2 = 400cm^2$

$\implies\bf side^2 = 400$

$\implies\bf side = \sqrt{400}$

$\implies\bf side = 20cm$

Therefore,

Side of square = 20cm

More to know :-

• Perimeter of square = 4 × side

• Area of square = side²

• Square is a regular quadrilateral having 4 sides and 4 vertices.

Answer 2

Answer:

The side of the square will be 20cm.

Step-by-step explanation:

Given: The area of the square is 400cm square.

We have to find the side of the square.

• As we know that the formula is used to calculate the area of the square is: $Area= side ^2$

We are solving in the following way:

We have,

The area of the square is 400cm square.

The side of the square will be:

$Area= side ^2$

Here, Area =$400cm^2$

So,

$Area= side ^2$

$=>400=side^2\\\\=>\sqrt{400} =Side\\\\=>Side=20\ \ \ [\because20\times20=400]$

Hence, the side of the square will be 20cm.
