Hi golchhamohit;

Is there anymore to the problem because I am getting multiple solutions?

Hi golchhamohit,

I can only get formulas for their relationships, not a numerical solution without more info as bobbym said.

Side lengths as follows:-

In descending order of board size:

In ascending order of board size:

Any value of x will give the 5 square feet differences between the boards' surface areas as per the puzzle wording.
