There are 2 perfect squares that are two-digit and divisible by 3.
To find the two-digit perfect squares that are divisible by 3, we can start by finding all the two-digit perfect squares and then check which ones are divisible by 3. The two-digit perfect squares are:
4: 16
5: 25
6: 36
7: 49
8: 64
9: 81
Now we can check which of these numbers are divisible by 3:
16: not divisible
25: not divisible
36: divisible
49: not divisible
64: not divisible
81: divisible
Thus, there are two two-digit perfect squares that are divisible by 3: 36 and 81.
So, the answer is 2.
