Formula for Area of a square:
[tex]\boxed {\boxed {\text {Area = Length x Length}}}[/tex]
Given that the area is 144 unit²:
[tex]\text {Length}^2 = 144[/tex]
[tex]\text {Length} = \sqrt{144} = 12 \text { units}[/tex]
Formula for Perimeter of a square:
[tex]\boxed {\boxed {\text {Perimeter = 4 x Length }}}[/tex]
[tex]\text {Perimeter = } 4 \times 12 = 48 \text { units}[/tex]
[tex]\boxed { \boxed { \text {Answer: The perimeter is 48 units.}}}[/tex]
