Which 2 digit numbers become 27 bigger when the digits are reversed?

Question

13 x 13 = 169 and 31 x 31 = 961.
Can you find other numbers which give answers in reverse order when they are reversed and multiplied by themselves?

Answer 1

10a+b - (10b+a) = 27
9a - 9b = 27
a - b = 3
This means if
b=1: 41 - 14 = 27
b=2: 52 - 25 = 27
b=3: 63 - 36 = 27
b=4: 74 - 47 = 27
b=5: 85 - 58 = 27
b=6: 96 - 69 = 27.
