Sum of squares of 15 and 14 = 152 + 142 = 225 + 196 = 421
The nearest perfect square is 212 (= 441).
Smallest number that should be added the sum of squares of 15 and 14, so that the resulting number is a perfect square = 441 – 421 = 20
∴ Smallest number that should be added the sum of squares of 15 and 14, so that the resulting number is a perfect square = 20
