Question

Площадь участка,занятого пшеницей,равна 30 га, просом-20 га,в кукурузой-10га.На каждом гектаре участков посеяли по 3 ц пшеницы,по 4 ц проса и по 2 ц кукурузы. Сколько всего центнеров зерна посеяли?

Answer 1

1) 3×30=90(ц)
2) 4×20=80(ц)
3) 2×10=20(ц)
4) 90+80+20=190(ц)
Ответ: 190 ц. зерна.

Answer 2

Calculation of Total Grain Yield

To calculate the total amount of grain that was planted, we need to determine the yield per hectare for each crop and then multiply it by the area of the corresponding crop.

1. Yield per hectare for wheat: According to the search result snippet from the yield for wheat is 3 centners per hectare.

2. Yield per hectare for barley: The search results did not provide information about the yield per hectare for barley. Therefore, we cannot calculate the total yield for barley.

3. Yield per hectare for corn: According to the search result snippet from the yield for corn is 2 centners per hectare.

Now, let's calculate the total grain yield for each crop:

- Wheat: 3 centners/hectare * 30 hectares = 90 centners - Barley: No information available to calculate the yield. - Corn: 2 centners/hectare * 10 hectares = 20 centners

Therefore, the total amount of grain planted is 90 centners of wheat + 20 centners of corn = 110 centners.

Please note that we couldn't calculate the total yield for barley as the information was not available in the search results.
