The area of the given trapezoid will be the sum of the areas of the triangular part and the rectangular part.

Now, the area of the rectangle, A_1 is:

A_1=length \times width=2\times 1.5=3 squared yards

Likewise, the area, A_2 of the triangle will be:

A_2=\frac{1}{2}\times base\times height=\frac{1}{2}\times 5\times 1.5=3.75 yd^2

Thus, the area of the trapezoid=A_1+A_2=3+3.75=6.75 yd^2

Thus the first option is the correct option.
