100
Step-by-step explanation:
100 is a perfect square . It is the square of 10.
The trick that can be used to find out perfect square here is that a perfect square can have 2 zeroes in the end like 100 , 900 etc. But this does not imply to all as 200 has 2 zeroes in the end but it is not a perfect square.
