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.
