Divide 489 from the last into pairs
4 89
Now Look for the least possible square for 4(First digit or pair?
2×2=4

Put the quotient as 2
And then multiply the quotient by 2.

2×2 × __=89
Make sure that the last digits are same for example,43×3,44×4,...

42×2=84(least possible)


89-84=5

The square root is 22.
