Question
A parallelogram has diagonals of lengths 24 cm and 18
cm. The angle between the diagonals is 60°. Find the area of the parallelogram.Solution
The area of a parallelogram can be calculated using the formula: Area = 1/2 × product of diagonals × sin of the angle between them. So, Area = 1/2 × 24 × 18 × sin 60°, Area = 1/2 × 24 × 18 × (√3/2), Area = 216 × √3/2 = 216 × 0.866 ≈ 187 cm². Answer: a
