If in coded language 4216 = 3, 1211 = 4, 9164 = 5 Then 1649 = ?

Question

If in a coded language
1.67 * 2.31 = 129
2.39 * 4.31 = 202
6.78 * 4.87 = 816
Then
7.16 * 9.13 = ?

Answer 1

4216 = 3 (number of perfect square in the number i.e. 4, 1, 16)
1211 = 4 (number of perfect square in the number 1, 121, 1, 1)
9164 = 5 (number of perfect square in the number 9, 1, 16, 64, 4, 1
Similarly
1649 = 6 (Perfect squares in the number are - 1, 16, 4, 64, 49, 9)
