Ответ:

длина участка=3км200м=3200м

3200×3/4=2400м ( ширина участка)

3200×2400=680000м2 (площадь участка)

680000×5/8=425000м2= 425км2=42500га (засеяли пшеницей)

680000-425000=255000м2 (остальная часть земли)

255000×5/6=212500м2=212,5км2

=21250га (засеяли кукурузой)

Ответ: пшеницей засеяли 42500га, кукурузой - 21250га.
