Someone pl explain why A cannot be the answer? If we map the triangle on a coordinate plane we have the base on X-axis and apex on Y-axis. Going by formula: Area = 1/2 (base x height) we have the base as 5 units and in order to have the area bigger than 15 we need the height to be >6 units. S1 says A<3, so height of triangle is <3 too hence area is less than 15. S1 SUFFICIENT - consider A=-10, what is the area then?

From S2 we know the triangle is right hence if the side on X-axes is 5 units the other 2 sides will be 3 & 4 units. Again, area <15. S2 SUFFICIENT If above are correct then answer is D. Comments welcome.

Hope that helps!

This certainly is very helpful, thank you & Bunuel!!

I suppose here D would be logical option My apporach Statement 1 A<3 now according to distance formula -1,0 and 4,0 distance is 5 therefore area 5A/2>15 , means A<6 hence SUFFICENT sTATEMENT 2RIGHT ANGLE if we take 3,4,5 triplet the area will be 3*4/2=6 and any subsequent relation gives area <15 Hence Sufficient Therefore D (Correct me if I am wrong )
