1) 200 * 0,78 = 156 ( м) - ширина участка
Теперь известна длина (а) и ширина. (b) Найдем площадь:2) sпр =аb = 200 * 156 = 31 200 ( м2)
вспахано 22 %, не вспахано: 100% - 22 = 78%, 78% площади это:3) 31 200 * 0,78 = 24 336 ( м2) - площадь вспаханого участка
Автор задачи просит дать ответ в гектарах1га = 10000м24) 24 336: 10000 = 2,4336 ≈ 2,5 га
ОТВЕТ: 2,5 ГА
