Answer:

Option A
15.5\ m^(2)

Explanation:

we know that

The area of the figure is equal to the area of a rectangle plus the area of semicircle

see the attached figure to better understand the problem

Step 1

Find the area of the rectangle

The area of the rectangle is equal to


A=bh

we have


b=6\ m


h=2\ m

substitute


A=6*2=12\ m^(2)

Step 2

Find the area of semicircle

The area of semicircle is equal to


A=(1)/(2)\pi r^(2)

we have


r=3/2=1.5\ m

substitute


A=(1)/(2)(3.14)(1.5^(2))=3.5\ m^(2)

Step 3

Find the area of the figure


12\ m^(2)+3.5\ m^(2)=15.5\ m^(2)
