Formula used :
(a + b - c)2 = a2 + b2 + c2 + 2ab - 2bc - 2ca
Calculations :
According to the question
⇒ a2 + b2 + c2 - 1024 = -2ab + 2bc + 2ca
⇒ a2 + b2 + c2 + 2ab - 2bc - 2ca = 1024
⇒ (a + b - c)2 = 1024
⇒ a + b - c = 32
Put a + b = 5c
⇒ 5c - c = 32
⇒ 4c = 32
c = 8
∴ Option 1 is the correct choice.
