![**Question 4:**
To the nearest hundredth, what is the area of a parallelogram whose sides are 20.8 cm and 10.9 cm long, if the measure of one of its angles is 53°?
**Explanation:**
To find the area \( A \) of a parallelogram when you know the lengths of two adjacent sides \( a \) and \( b \), and the angle \( \theta \) between them, you can use the formula:
\[ A = a \times b \times \sin(\theta) \]
In this problem, the sides are \( a = 20.8 \, \text{cm} \) and \( b = 10.9 \, \text{cm} \), and \( \theta = 53^\circ \).
Calculate the area using the sine function for the given angle.](https://content.bartleby.com/qna-images/question/b9e6f454-aef3-4078-bf5c-8f7a3cacb5c5/639aa7aa-ba49-4244-96c7-a910167ff6fb/cswpt2t_processed.png)
