Area of the semicircle = \(\frac{\pi r^2}{2}\) Since Radius is 2 therefore Area of the semicircle =>\(\frac{\pi*2*2}{2}\)===> \(2\pi\) Area of the rectangle=\(l . b = 8 x 4 = 32\)

total area = \(32 + 2\pi\) Answer is E

Here are a couple of videos about this problem. The first goes over a shortcut method to solve the question in a few seconds. The second goes over a more conventional, but more versatile, approach.

I see this differently. If this was purely a rectangle, then the area would be 40sq.f

So A and B are automatically wrong. Say I don't remember my geometry and only know that pi is 3.14, then everything is easy. C=32+8*3.14=too much D=32+4*3.14=too much

So by elimination the answer is E

Did it the same way.

Half-circle --> 2/pi, we can narrow down the choices to two. If it would be a full rectangle --> 4 * 10 = 40. But it is not a full rectangle. --> Must be E.
