With a roller shear, rectangular sheets of

1420

mm wide should be made, namely with a width of

500

mm and a total length of

1000

m as well as a width of

300

mm and a total length of

1800

m can be cut. So far it has been based on the attached drawing cut, in which the gray area represents the waste, which is quite large. A socialist brigade proposes cutting in such a way that waste is significantly reduced becomes. a) What percentage is the waste if cutting continues as before? b) How does the brigade have to cut so that the waste is as small as possible and what is the total length of the starting sheets is required in this case? c) What percentage is the waste now? https://cdn.artofproblemsolving.com/attachments/f/8/c6c88b79abb5d34674bf54524ae1731985c3f7.png
