The area of the Δ  ABC\Delta \;ABC, in which a=1,b=2,∠C=60∘a = 1,b = 2,\angle C = 60^\circ, is
View answer and explanation
Correct option: C
32  sq  unit\frac{{\sqrt 3 }}{2}\;\mathrm{sq }\;\mathrm{unit}
Option C (32 sq unit\frac{{\sqrt 3 }}{2}\,\mathrm{sq }\,\mathrm{unit}) is correct because the area of a triangle can be found using the formula 12absin⁡C\frac{1}{2}ab\sin C when two sides and the included angle are known.
