Step-by-step explanation:
Answer:
A and D
Step-by-step explanation:
Given

= ± 
= ±
× 
= ± 6i
That is - 6i or 6i
Area of a triangle = b*h/2
B=6
H=6
6*6=36
36/2= 18
A=18 cm
It is not possible because the triangle isn't fixed. Then second and third side can being an infinite possible number of lengths, therefore making this problem impossible to solve.
