Given: ABCD is a parallelogram AB=15cm and AD=8cm∠BAD=θ Formula Used: If a and b are adjacent sides and θ is the angle between them Then the area of parallelogram =ab‌sin‌θ Calculation:
According to the formula used Area of parallelogramm ABCD is AD×AB×sin‌θ ⇒ Area of ABCD=8×15×sin‌θ ⇒ Area of ABCD=120‌sin‌θ ∴ The area of parallelogram ABCD is 120‌sin‌θ‌cm2.
