Question 3

Answer 1

Answer:

Area = 19.05 feet squared

Step-by-step explanation:

By applying sine rule in ΔABC,

sin(∠CAB) = $\frac{\text{Opposite side }}{\text{Hypotenuse}}$

sin(60°) = $\frac{BC}{AC}$

$\frac{\sqrt{3}}{2}=\frac{BC}{4}$

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.
