To satisfy the ABOVE condition ----> decreasing 2 parallel sides by 2cm and increasing the other by 12cm to formed the Area of the rectangle:
Remember: For the Square,
For the Rectangle, , &
Therefore, going back working eqn
----------------------> eqn 1

, perfect square

2 values:
SO THE SIDES OF THE SQUARE COULD BE 6CM OR 4CM. TO CHECK, SIMPLY SUBSTITUTE EITHER S=6CM OR 4CM TO EQN 1.
Thank you,
