a=

144

=12

Answer 2

Step-by-step explanation:

We know that the Area of square → Side × Side = (Side)²

Let the sides of the square board be x.

→ Area of square board = 144 units²

→ (Side)² = 144 units²

→ x² = 144 units²

→ x = √(144 units²)

→ x = 12 units

Therefore, each side of the square board is of 12 units.
