Answer:

27.93 square yard

Step-by-step explanation:

For semicircle:

Radius (r) = 7 yards

For Triangle:

b = 2r = 2*7 = 14 yd

h = 7 yard

Area of shaded region = Area of semicircle - Area of triangle

$= \frac{1}{2} \times \pi {r}^{2} - \frac{1}{2} \times b \times h \\ \\ = \frac{1}{2} \times 3.14 \times {7}^{2} - \frac{1}{2} \times 14\times 7 \\ \\ = \frac{1}{2} \times 3.14 \times 49 - \frac{1}{2} \times 98\\ \\ = 3.14 \times 24.5 - 49 \\ \\ = 76.93 - 49 \\ \\ = 27.93 \: {yd}^{2} \\$
