It’s D 58.3^2
Explanation:
to find the area of a square you use the formula l*w so in this case it would be 5*6 which is 30
To find the area of the half circle you use the formula A=3.14r^2
The diameter of the half circle is 6 so that means the radius is 3 so 3^2 is 9 and 9*3.14 is 28.26z
28.26+30=58.3
Hope this helped!!
