ANSWER

d. 661.9 {yd}^{2}

EXPLANATION

The area of the given triangle can be calculated using the formula,

Area= \frac{1}{2} bc \sin(A)

Where b=54yd , c=54yd,and A=27° is the included angle.

We plug in these values to get;

Area= \frac{1}{2}  \times 54 \times 54 \sin(27 \degree)

Area=661.9 {yd}^{2}

The correct answer is D.
