1 часть площади участка выделили под морковь, 3 части площади участка - под картофель. Всего 4 части.

200 : 4 = 50 кв.м - площадь, занятая морковью (1 часть)

50 * 3 = 150 кв.м - площадь, занятая картофелем (3 части)

Проверка: 50 + 150 = 200

Ответ: 150 кв.м под картофель и 50 кв.м под морковь.

х+3х=200
4х=200
х=200:4=50м²-под морковь
3*50=150м²-под картофель
