Answer» Correct Answer - Option 2 : 54 sq. cm

Given:

Two adjacent sides of a parallelogram are 12 cm and 9 cm.

And one of the angle is 30°

Formula used:

Area of parallelogram = ab × sinθ  

Where, a and b are two adjacent sides.

Calculation:

a = 12 cm

b = 9 cm 

θ = 30° 

Area of parallelogram = ab × sinθ 

⇒ 12 × 9 × sin30° = 12 × 9 × (1/2)

⇒ 6 × 9 =54 cm2

∴ The area of parallelogram is 54 cm2.
