Photographing stars requires you to keep your exposure open for a long time. Taking pictures of star trails would take about 30 minutes to three hours. If you multiply that for the 6 stars stated above in the problem then you would be needing that much time if the stars were close and approximately 3 to 18 hours capture their star trails if they were far apart from each other.
        
             
        
        
        
First we have 2 types of units of measurement so let’s make all the same type. 
600mm= 60 cm
500mm= 50 cm
Tray dimensions are 60 by 50 cm and is a rectangle 
Cake tin is round and has diameter 25 cm
We can fit 2 rows and 2 columns of tins
Since (25+25) is less or equal to 50
 And (25+25) is less or equal to 60
Answer 4 cake tins

She cut it into 4 parts, so 28/4=7 cm
Her rope was 7 cm long.
Hope this helps you.
