there's an unshaded area underneath the rectangle

anonymous · Answer

I know that...it is supposed to be a full rectangle...the teacher messed it up...

nincompoop · Answer

well here's how you will break it down
get the area of the rectangle
A = base*height

then with the dome looking shape, that's essentially a semi-circle
use the formula for the area of a circle 
A = pi *r^2 but use the base length of the rectangle as your radius
and since it is half a circle, you would do 
A = (pi * r^2)/2

anonymous · Answer

I did that...so i guess I am right...

nincompoop · Answer

once you've accomplished both task, add the areas 
total area = area of rectangle + area of semi-circle
