What information relevant to calculating are do we have available for this triangle?

Well, since we are not given any graphics or additional information, I'll resort to listing four triangle area formulas:

1) triangle area = (1/2) * base * height

2) Heron's Formula  ("s" = semiperimeter, which is the sum of all 3 sides divided by two)

triangle area = square root [s * (s - side a) * (s - side b) * (s - side c)]

3) For 2 sides and the INCLUDED Angle:

Area = side 1 * sine (angle A) * side 2

Step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

sorry

sorry, but im pretty sure its a now that i look at it
