Please tell me answer of this question in easy way but Step-by-step explanation ​

Answer 1

6.5×6.5=42.25

-9×6.5=58.5

4.5×4.5=20.25

42.25-58.5+20.25=4

4^2=2

n=2

Answer 2

Hey bro!
6.5 × 6.5 = 42.25
- 9(6.5) = 58.5
+ (4.5)(4.5) = 20.25,
So, according to the question,
=42.25 - 58.5 +20.5= 4,
4 = n square,
Hence, n=2,
