ABCD is a parallelogram with AB = 15 cm and AD = 8 cm. If θ is the acute angle between AB and AD, then what is the area of the parallelogram in square cm?
Elementary MathematicsQuadrilaterals and Polygons
- A60 sin θ
- B120 sin θ
- C60 cos θ
- D120 cos θ
Explanation
Area of a parallelogram = (side)(side)sin(included angle) = 15x8xsinθ = 120sinθ. Hence the keyed option is B.
