Question

длина земельного участка имеющего форму прямоугольника равна 750 м,а ширина 150 м. Сколько семян понадобится, чтобы засеять весь участок,если для 1 на участка нужно 80 кг семян​

Answer 1

1) S = 750 × 150 = 112500(м²)

112500м² = 11,25га

2) 80 × 11,25 = 900 (кг) — семян.

Ответ: 900кг.

Answer 2

Calculating the Number of Seeds Needed to Sow the Entire Plot

To calculate the number of seeds needed to sow the entire plot, we can use the formula:

Number of seeds = Area of the plot / Area covered by 1 kg of seeds

Given: - Length of the plot = 750 m - Width of the plot = 150 m - Seeds needed for 1 m² of the plot = 80 kg

Calculation

The area of the plot can be calculated using the formula: Area = Length × Width

Substituting the given values: Area = 750 m × 150 m

Now, we can calculate the number of seeds needed using the formula: Number of seeds = Area / Area covered by 1 kg of seeds

Let's calculate the area of the plot and the number of seeds needed.
