Answer:

-Area of square = 144 yd²

-Area of semi circle = 56.5 yd² (rounded to nearest 10th)

Step-by-step explanation:

Area of square = 12 × 12

= 144 yd²

r of semi circle= 12÷2= 6yd

Area of semi circle

[tex] = \frac{1}{2} \pi {r}^{2} \\ = \frac{1}{2} \times \pi \times {6}^{2} \\ = \frac{1}{2} \times \pi \times 36 \\ = 18\pi [/tex]

= 56.54866.....

= 56.5 yd²
