I've put 74.8 and 56 as my answers. I know the circumference is like the perimeter so I added with the 56 at first but it turned out to be wrong. So then I just put 56 and that also was wrong.

Step-by-step explanation:

Area of Rectangle+ Area of semi-circle = Total area of composite figure

Area of rectangle = l*b = 12*16 ft² = 192 ft²

radius = 12/2 = 6

Area of semi circle = 1/2* π* r² = 1/2*3.14*6²= 56.52 ft

Total area = 192+56.52 = 248.5 ft²

Total Perimeter = 16*2 + 12+π*12 = 81.7 ft
