Are you serious, or your post is a kind of joke ?
If you are serious, you should provide a picture, or give a link to a picture, or, at least,
to say, using your own words, to which side of the rectangle the semi-circle is joined.
I am very surprised to see this message, which pretends to be a Math problem,
prepared so carelessly . . .

Hello, I got your comment and read it.
Let me tell you in response, that when somebody points you on your error,
then the only right way to react on it is to say " Thank you ".
It is an ELEMENTARY RULE and THE ONLY WAY to follow for a normal adequate person.
Usually, parents (a mother, a father) or relatives teach a young child to this basic rule from the early age.
So, normally, at the age of 7 years this conception is just has to be
in the head of a child; and at the age of 9 years it should work in automatic mode.
It is the normal human adequate reaction.

It depends if the diagram is this
OR if it's this
If it's the 1st diagram, then the semicircular area is
(1/2)*pi*r^2 = (1/2)*pi*6^2 = 18pi square feet.
That approximates to 18pi = 18*3.14 = 56.52 square feet
Add that onto the rectangular area of 12*20 = 240 square feet.
240+56.52 = 296.52
The total area in the 1st figure is approximately 296.52 square feet.
If on the other hand the diagram was the 2nd one I've shown above, then:
semicircle area = (1/2)*pi*r^2 = (1/2)*pi*10^2 = 50pi = 50*3.14 = 157
rectangular area = 12*20 = 240
total approximate area = 240+157 = 397 square feet
Both involve 240, but the difference is the semicircular area.
