for right angled
c^2 = a^2+b^2
target 1/2 * ( a*b)
#1 \(\frac{(a+b)^2-c^2}{8}=3\)
c^2+2ab-c^2 = 24
ab=12
area is 6
sufficient
#2
c=5
∆ can be 45:45:90 or 30:60:90
insufficient

(2) \(c=5\)
Right Angle triangle,
a^2+b^2 =c^2 (c=hypoteneuse)
Area= 1/2 * (a*b)
St1:
a^2+b^2+2ab - c^2 = 24
c^2+2ab-c^2 = 24
ab=12
Area= 1/2 * (a*b)
Area=6
Sufficient
St 2:
c=5
Can have different area.
Insuff.
