We know that 10x10=100
Then just square the whole numbers greater than 10 until it exceeds the limit that is 500.

10x10=100, Not included (should be between 100 and 500)
11x11= 121, /
12x12= 144 , /
13x13= 169  , /
14x14=  196,/
15x15= 225,/
16x16=256,/
17x17=289,/
18x18=324,/
19x19= 361,/
20x20= 400,/
21x21=441,/
22x22=484,/
23x23=529, Not included ( should be between 100 and 500)

Therefore the perfect squares between 100 and 500 are:
121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, and 484.
(There are 12 of them.)   (Let me know if I have a mistake.)
