Arada [10]

Formula for Area of a square:

$\boxed {\boxed {\text {Area = Length x Length}}}$

Given that the area is 144 unit²:

$\text {Length}^2 = 144$

$\text {Length} = \sqrt{144} = 12 \text { units}$

Formula for Perimeter of a square:

$\boxed {\boxed {\text {Perimeter = 4 x Length }}}$

$\text {Perimeter = } 4 \times 12 = 48 \text { units}$

$\boxed { \boxed { \text {Answer: The perimeter is 48 units.}}}$
