The sides now are 12 cm because 12 x 12 is 144, but that is after they were lengthened 8 cm. The original square was 4 by 4.

It’s a square, so if you take the square root of the area to get the length of each side with the additional 8cm added. Then just subtract the 8cm from the result of the square root to get the answer.
If you don’t know what a square root is, look for a number that is equal to 144 when it is mulitplied by itself.

4 cm. because if it was lengthened by 8 and the area became 144cm^2, then the new side lengths would be 12. 12-8= 4.
