       FIG.  15    is a flowchart illustrating an operation of an electronic device according to an embodiment of the disclosure.  FIG.  15    may be described with reference to areas (e.g., a first area  1601 , a second area  1602 , a third area  1603 , a fourth area  1611 , and a fifth area  1612 ) of the display  160  in  FIG.  16   . 
     Referring to  FIG.  15   , according to an embodiment, in operation  1510 , an electronic device (e.g., the electronic device  101 ) may detect a positional relationship between a first housing (e.g., the first housing  210 ) and a second housing (e.g., the second housing  220 ). 
     According to an embodiment, the electronic device  101  may relatively compare the angle of the first housing  210  with respect to the ground surface with the angle of the second housing  220  with respect to the ground surface by using the sensor module  176  according to control of the processor  120 , thereby detecting (or identifying) the positional relationship between the first housing and the second housing  220 . For example, the electronic device  101  may compare the angle of the first housing  210  with respect to the ground surface with the angle of the second housing  220  with respect to the ground surface according to control of the processor  120 , thereby detecting (or identifying) the angle between the first housing  210  and the second housing  220 . 
     In an embodiment, the electronic device  101  may detect the distance between the first housing  210  and the second housing  220  by using the sensor module  176  according to control of the processor  120 , and may identify the angle and the positional relationship between the first housing  210  and the second housing  220 , based on the detected distance. 
     In an embodiment, the electronic device  101  may define a positional relationship between the first housing  210  and the second housing  220  by using an angle range according to control of the processor  120 . For example, a case where the angle between the first housing  210  and the second housing  220  is 0 degrees (e.g., the rear surface of the first housing  210  faces the rear surface of the second housing  220 ) may be defined as a first positional relationship. As another example, a case where the angle between the first housing  210  and the second housing  220  is 180 degrees may be defined as a second positional relationship. In addition, a case where the angle between the first housing  210  and the second housing  220  exceeds 0 degrees and is smaller than 180 degrees may be defined as a third positional relationship.

A content display area according to control of the processor  120  of the electronic device  101  may not be limited to the above description. 
     In an embodiment, the electronic device  101  may deactivate an area in which a content is not displayed, in case that a particular area of the display (e.g., the display  160 ) is activated and a content is displayed therein, according to control of the processor  120 . For example, in a case of the first positional relationship, the electronic device  101  may deactivate the third area  1603  not to display a content while displaying a content in the first area  1601 , the second area  1602 , or the fifth area  1612  according to control of the processor  120 . In this case, the electronic device  101  may maintain a state for reactivation while deactivating the third area  1603 , according to control of the processor  120 . 
     In an embodiment, the electronic device  101  may activate the third area, based on the maintained state, when the electronic device is to reactivate the third area  1603 , according to control of the processor  120 .
