225 is a perfect squarebecause 225 = 15*15
Technically, every positive number is a square in the real number system, but I assume you mean perfect square. And yes, 225 is a perfect square. 152 = 225
15
225
152 = 225, and 162 = 256 So there can be no integer, k, such that k2 = 250 and that is what defines a perfect square.
The next perfect square after 196 is 225. This is because 196 is the square of 14 (14 x 14), and the next integer is 15. Squaring 15 gives 15 x 15 = 225.

25, 49, 81, 225
to find the no. of non prefect squares is the square of 15 is 225 and the square of 16 is 256. We need to subtract the square of 15 and 16 256 ( 16 ) -225 (15 )= 31 Therefore there are 31 non perfect squares. Hop you understand
Oh, dude, let me put on my detective hat for this riveting mystery. So, Sally likes numbers that are perfect squares but not numbers that are just one more than a perfect square. In this case, she must like 144 because it's a perfect square, but not 145 because it's just one more. Case closed, Sherlock.

225 is a square number.
