    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.
