How many perfect squares are there between 200 and1000?

Answer 1

14^2 = 196

31^2 = 961

Answer 2

1st perfect square number between 200 and 1000 is 225 = 15 * 15.
And last perfect square number is 961 = 31 * 31.

So:

( 31 - 15 )+ 1 = 16 + 1 = 17

225 = 15 * 15
256 = 16 * 16
289 = 17 * 17
324 = 18 * 18
361 = 19 * 19
400 = 20 * 20
441 = 21 * 21
484 = 22 * 22
529 = 23 * 23
576 = 24 * 24
625 = 25 * 25
676 = 26 * 26
729 = 27 * 27
784 = 28 * 28
841 = 29 * 29
900 = 30 * 30
961 = 31 * 31
