Answer: 51.96 cm^2 (Use Area Formula).
Step-by-step explanation:
Area = (1/2) x a x b x sin C
Area = (1/2) x (12) x (10) x (sin 120)
= 60 x (sin 120)
= 51.96 cm^2.

here s = semiperimeter = 41.1/2 = 20.6 cm
Area = √[s(s-a)(s-b)(s-c)]
= √[20.6(20.6-10)(20.6-12)(20.6-19.1)]
= √[20.6×10.6×8.6×1.5]
= √3348.32
AREA = 57.9 cm²
