Step-by-step explanation:
Using formula:
Calculating rectangle area:
[tex]A=lw[/tex]
[tex]=15 \times 8\\\\=120[/tex]
Calculating semicircle area:
[tex]A=\frac{1}{2} \pi r^2\\\\[/tex]
[tex]=\frac{1}{2} \times \pi \times 7.5^2\\\\=\frac{1}{2} \times \pi \times 56.25\\\\=28.125\ \pi \\\\=28 \ \pi[/tex]
Total area:
