To determine the Area, we need to uniquely determine a & b sides of the triangle.

(1) Sum of the sides is known but each side is not. Insufficient.

(2) $$c^2 = a^2 + 36$$ on comparing with the Pythagoras theorem for this triangle:$$b^2 = 36$$ or $$b = 6$$ However, we do not know a. Insuff

(1) + (2) : we know b from (2) and we can find a as (1) gives us the sum of a & b. Sufficient!

Hence Option (C) is correct.

Best,
