find the approximate perimeter of the figure. use 3.14 for pi and round you answer to the nearest tenth

we have that
The approximate perimeter of the figure is equal to the circumference of a complete circle plus the perimeter of a rectangle minus two times the diameter of the circle
so
diameter=12-6=6 ft
P=pi*6+2(12+3)-2(6)
P=3.14*6+30-12
