Answer: d

Step-by-step explanation:

Find the area of the rectangle.

[tex]A=l*w\\A=(15in)(12in)\\A=180in^2[/tex]

Find the area of the base of the semicircle.

[tex]A=\pi r^2[/tex]

12 in would be the diameter, divide by 2 to get the radius.

[tex]\frac{12}{2}=6[/tex]

Plug this into the formula.

[tex]A=(3.14)(6)^2\\A=113.04in^2[/tex]

Since we do not have a full circle but a semi one instead, we must divide our result by 2.

[tex]\frac{113.04}{2}=56.52in^2[/tex]

Add both areas.

180+56.52=236.52[tex]in^2[/tex]
