Ok, so you need half the area of a circle with radius 4 cm. The area of a rectangle is A = LW, where L = length and W = width

A = pi x r^2

Right. Calculate that and divide by 2 because you have only half a circle. Then add that to A = LW, with L = 8 cm and W = 5 cm, which is the area of the rectangle.

That's good. You have the area of the half circle. Now you need to calculate the area of the rectangle and add the two areas.

So 40 + 25.2 = 65.3. That's the answer?

But 65.3 isn't an answer choice.
