The square of 13 and 31 are 169 and 961.

The number which tenth digit A and unit digit B is 10A+B. The other number is 10B+A.

The square of the first number is (10A+B)^2=100A^2+20AB+B^2. Each digit is A², 2AB, B², and it has to be less than 10.

→ A=1, 2, 3

→ B=1, 2, 3

23 and 32 can't be an answer since their 2AB is 12.

The numbers are 12, 13, 21, 31.

Verification 1: 12²=144, 21²=441

Verification 2: 13²=169, 31²=961
