Depending on x being 1,2,3,4or 5, the side length of other piece would be 9,8,7,6,or 5 cms respectively.
Explanation:
Essentially, the question is to find two numbers, sum of four times of whose square roots is 40. these square numbers are (1,81); (4,64); (9,49),(16,36)and (25.25).
The side lengths of square pieces can thus be ( 1 and 9); (2 and 8); (3 and 7); (4 and 6) r (5 and 5). Thus depending on x being 1,2,3,4or 5 cms, the side length of the other square would be 9,8,7,6 or 5cms respectively.
