Answer 2

Answer:

$189.25 \: {cm}^{2}$

Step-by-step explanation:

Area of the shape = Area of rectangle + Area of semicircle.

For rectangle:

Length = 15 cm

Width = 10 cm

For semicircle:

Diameter = 10 cm

Radius = 10/2 = 5 cm

Area of the shape

$= lb + \frac{1}{2} \pi {r}^{2} \\ \\ = 15 \times 10 + \frac{1}{2} \times 3.14 \times {(5)}^{2} \\ \\ = 150 + \frac{1}{2} \times 3.14 \times 25 \\ \\ = 150 + 39.25 \\ \\ = 189.25 \: {cm}^{2}$
