Why does this area leak?

[lemelman]

I have a simple sketch - basically a rectangle with a circle tangent to two sides. The circle effectively divides the rectangle into three areas. See attached screenshots.

I want to select areas 1 & 2 in order to delete them. I can select area 2 OK, but when I select area 1 it includes area  3 and the the circle. Why can't I select area 1 alone? I've tried adding the F3D but I get an error message saying 'Sorry, unable to complete the action you requested.'

There are several lines on top of each other.

Just delete them.

I apologise fore my delayed response, I have been unable to use my system for several days. Thank you for identifying my error and showing how to fix it. It was most mystifying.

So if you have no further questions please mark it as solved.
