Two options using A and B : 10,10, 12 or 12,12,10
area = sqrt( s * s-a * s-b *s-c) , s = a+b+c / 2;
E it shall be
area = sqrt( s * s-a * s-b *s-c) , s = a+b+c / 2;
E it shall be

(1) Triangle ABC is isosceles does not give us the area of triangle ABC. So, (1) is NOT SUFFICIENT.srcc25anu wrote:What is the area of triangle ABC?
(1) Triangle ABC is isosceles.
(2) AB= 10 and BC = 12
(2) We are given the length of 2 sides of triangle ABC. But again this is NOT SUFFICIENT.
Combining (1) and (2), we don't whether AC = 10 or 12. So, again combining is NOT SUFFICIENT to answer the question.
The correct answer is E.
