Yes, the another formula for area of a triangle is $= \frac{1}{2} ab \sin C$.

where a and b are two sides and C is included angle. Please mention the exact problem. Do you need to prove this formula or what???

The formula for arrea of a triangle is

Area of triangle ABC $= \frac{1}{2}ab \;\sin C$

Area of triangle ABC $= \frac{1}{2}bc \;\sin A$

Area of triangle ABC $= \frac{1}{2}ca \;\sin B$

Please DO NOT DOUBLE-POST the same question again. It wastes everybody's time.
