The perfect square = 225 × 225 = 50625 + 105 = 50730
Option (B) is correct.
Step-by-step explanation:
- By subtracting 205 from 50730 we get 50525 = if we square then we get ( 224.7 ) = it is not a square.
- Similarly by subtracting 105 from 50730 then we get 50625 = if we square then we get ( 225 ) = it is a square
- Then by subtracting 110 from 50730 then we get 50620 = if we square then we get ( 224.9 ) = it is not a square .
