Correct Answer: $12 \sqrt{2} \mathrm{~cm}$
Solution : According to the question, The area of the square is 144 cm 2 ⇒ Area = (Side Length) 2 = 144 cm 2 ⇒ side = $\sqrt{144}$ = 12 cm ⇒ Length of diagonal = $\sqrt{2}$ × Side length = 12$\sqrt{2}$ Hence, the correct answer is $12 \sqrt{2} \mathrm{~cm}$.
