Answer:

98.1 units

Step-by-step explanation:

so the area of the rectangle is 6x8 = 48

the are of one of the triangles is 4.5x8 = 18

so two of those...

then the area of the circle 6xpi = 28.2 but we have to cut it in half since its a perfect semi-circle... so 28.2/2 = 14.1

then we just add them all up, and we get

48+18+18+14.1 = 98.1

I hope this helps :)
