Answer 1

Answer:

The answer is "148 ft".

Step-by-step explanation:

Using formula:

Calculating rectangle area:

$A=lw$

   $=15 \times 8\\\\=120$

Calculating semicircle area:

$A=\frac{1}{2} \pi r^2$

   $=\frac{1}{2} \times \pi \times 7.5^2\\\\=\frac{1}{2} \times \pi \times 56.25\\\\=28.125\ \pi \\\\=28 \ \pi$

Total area:

$=120+28\\\\=148$
