Explicación paso a paso:

Each side of the board is of 12 cm.

Step-by-step explanation:

It's being given that, the board is a square,

so it means that each side is equal.

And the area of board is 144 sq. units.

So, we know the formula to find the area of a square, which is side².

Now, as the value of side is unknown, we will name it x (as you want).

So, ATQ

x² = 144

x = √144

[·.· 12² = 144]

...x = 12

Hence, each side of this board is of 12 units.

What are squares?

When a number is multiplied by itself, then the resultant number is a square of the initial number, vice-versa, the product of a number, when it is multilpied by itself is its square root.

Vice-versa, you may conclude that, square roots are the area of a square.
