The problem statement is ambiguous and since the question specifies an "8-meter square pool", we assume it means "8 square meters" and we further assume it starts off as a square pool, hence each side is "square root of 8". The area of Jem Boy after increasing the length and decreasing the width each by 2m would be:
(sqrt(8)+2)((sqrt(8)-2)
3.9997
So the new area would be approximately 4 square meters.
