Answer:
Area = 19.05 feet squared
Step-by-step explanation:
By applying sine rule in ΔABC,
sin(∠CAB) = [tex]\frac{\text{Opposite side }}{\text{Hypotenuse}}[/tex]
sin(60°) = [tex]\frac{BC}{AC}[/tex]
[tex]\frac{\sqrt{3}}{2}=\frac{BC}{4}[/tex]
BC = 2√3
Area of a parallelogram is given by the formula,
Area = Base × Height
= 5.5 × 2√3
= 11√3
= 19.05 ft²
Therefore, answer is Area = 19.05 ft squared.
