Question

На опытном участке длиной 20 м и шириной 15 м вырастили новый сорт пшеницы. С каждого ара было собрано в среднем по 46 кг зерна. Сколько центнеров зерна при такой средней урожайности можно было бы получить с 1 га?

Answer 1

30 кг моё мнение, мб не правильно ;)

Answer 2

1) 20 х15 = 300 кв.м площадь участка  300 кв.м = 3 а 

2) 46 х 3 =138 кг собрали со всего участка

3) 1га = 100 а

4) 46 х 100 = 4600 кг соберут с 1 га 

Answer 3

Calculating Grain Yield from Experimental Plot

To calculate the grain yield from the experimental plot, we can use the following information:

- Length of the plot: 20 m - Width of the plot: 15 m - Average grain yield per are: 46 kg

First, let's calculate the area of the plot in square meters:

Area = Length × Width Area = 20 m × 15 m Area = 300 square meters

Now, let's convert the grain yield from kg per are to kg per square meter:

1 are = 100 square meters So, 46 kg per are = (46 kg / 100 m²) per square meter 46 kg per are = 0.46 kg per square meter

Now, we can calculate the total grain yield from the plot:

Total grain yield = Average grain yield per square meter × Total area Total grain yield = 0.46 kg/m² × 300 m² Total grain yield = 138 kg

So, with the given average yield, the total grain yield from the experimental plot would be 138 kilograms.

Converting to Centners per Hectare

To convert the total grain yield from kilograms to centners and the area from square meters to hectares, we can use the following conversions:

1 hectare = 10,000 square meters 1 centner = 100 kilograms

First, let's convert the total grain yield from kilograms to centners:

Total grain yield in centners = Total grain yield in kilograms / 100 Total grain yield in centners = 138 kg / 100 Total grain yield in centners = 1.38 centners

Now, let's convert the area from square meters to hectares:

Total area in hectares = Total area in square meters / 10,000 Total area in hectares = 300 m² / 10,000 Total area in hectares = 0.03 hectares

Finally, we can calculate the grain yield per hectare:

Grain yield per hectare = Total grain yield in centners / Total area in hectares Grain yield per hectare = 1.38 centners / 0.03 hectares Grain yield per hectare = 46 centners

So, with the given average yield, the grain yield per hectare from the experimental plot would be 46 centners.
