Answer:
46.8
Step-by-step explanation:
Since we know two sides and a angle included between it we use this formula
[tex] \frac{1}{2} (12)(9) \times \sin(120) [/tex]
[tex] \sin(120) = \frac{ \sqrt{3} }{2} [/tex]
[tex]54 \times \frac{ \sqrt{3} }{2} [/tex]
[tex] \frac{54}{1} \times \frac{ \sqrt{3} }{2} = \frac{54 \sqrt{3} }{2} = 27 \sqrt{3} [/tex]
which about 46.8
