    and the included angle between them is 60°. Find the area of the parallelogram.
    A 10√3 cm² Correct Answer Incorrect Answer
    B 40√3 cm² Correct Answer Incorrect Answer
    C 20√2 cm² Correct Answer Incorrect Answer
    D 30√2 cm² Correct Answer Incorrect Answer

    Solution

    Area = ab sinθ Here a = 10, b = 8, θ = 60° sin60° = √3/2 Area = 10 × 8 × √3/2 = 80 × √3/2 = 40√3 cm².
