The adjacent sides of a parallelogram are 10 cm and 8 cm and the angle between them is 150°. What is the area of the parallelogram?
- A. 40\sqrt{3} square cm
- B. 40 square cm ✓
- C. 20\sqrt{3} square cm
- D. 20 square cm
Correct Answer: B. 40 square cm
Explanation
Area of a parallelogram = a \times b \times \sin\theta = 10 \times 8 \times \sin(150^\circ) = 80 \times 0.5 = 40 sq cm.
