Area = 19.05 feet squared
Step-by-step explanation:
By applying sine rule in ΔABC,
sin(∠CAB) = ![\frac{\text{Opposite side }}{\text{Hypotenuse}}](/tpl/images/1180/5661/9addf.png)
sin(60°) = ![\frac{BC}{AC}](/tpl/images/1180/5661/e8eaf.png)
![\frac{\sqrt{3}}{2}=\frac{BC}{4}](/tpl/images/1180/5661/b4dee.png)
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.
