hitunglah luas dan kelilingnya​

I did another one just like this about an hour ago. I did it the elegant, tedious way, and it took about 2 feet of screen. Then I realized there was a totally bourgeois but easy way to do it. For 5 points, I'll give you the method for the masses:
List all the possible pairs of digits that add up to 9, along with their flips:
18 . . . . . 81 27 . . . . . 72 36 . . . . . 63 45 . . . . . 54
Do you see any pair that are different by 27 ? How about 36 and 63 ?
So the original number is 63, and when you flip it, it becomes 36, which is 27 less.

The original two-digit number is 63. This is confirmed by the fact that the digits sum to 9 and reversing the digits gives a number that is 27 less. Therefore, the answer to the problem is 63.
