Correct answer is : Area of triangle is
Solution:-
We can do it in 2 methods.
Method 1:-
Given that AB=6, BC=10 and m∠B = 120
Then area of triangle =
Let us assume AB is base and D is an altitude from C onto AB.
Then sin(60)=
CD = BC sin(60)
Hence height = =
Hence area of ΔABC = sq.units
Method2:-
Area of triangle =
Here a= BC=10, c=AB=6.
Hence area of triangle = sq.units
