# 13.5 Calculating Areas and the Sine Rule

The sine rule for the area of a triangle is Area = Â½ ab sinC, where â€˜aâ€˜ and â€˜bâ€˜ are two sides of a triangle and â€˜Câ€˜ is the angle in between them. In this section, we learn about sine and cosine rules, sine rule, discussion of the sine rule in a general triangle, use the sine rule to find the missing side, use the sine rule to find the missing angle, area of triangle.

If you're a student in a school/college that's based in England, you might be entitled for full access to our eLearning platform where you can access to all our tutorial videos and practice questions.

Please check with the head of Maths or deputy headteacher at your school/college to request access if they've already registered to our free pilot subscription. They can always reach us at the below email:

The sine rule for the area of a triangle is Area = Â½ ab sinC, where â€˜*a*â€˜ and â€˜*b*â€˜ are two sides of a triangle and â€˜*C*â€˜ is the angle in between them. In this section, we learn about sine and cosine rules, sine rule, discussion of the sine rule in a general triangle, use the sine rule to find the missing side, use the sine rule to find the missing angle, areaÂ of triangle.
