select location and attribute

[GizemÇoban]

Hello, I have a polygon

 shape file with the basin boundaries of a country. the attribute table contains basin names and areas. at first I need to select places with an area less than 10000km2. I did this with select attribute and created a new polygon. then I need to select the basins with an area less than 10000km2 and the locations of the basins with each other are less than 50km. but I don't understand how to do this with select location. if you can help me, I would be very grateful.

It is still a select by attributes, but 50km is a distance, is it the perimeter or length that you are after?

Hello GizemÇoban,

Please refer to Dan Patterson's reply.  But I did want to ask you about the km2 and km values you have in your attribute table.  For e.g. Akarcay Havzasi, you have values km2 = 7982,57882 and km = 553,55355.  Are these values correct?  The comma position seems out of place and missing a comma.
