Question

в фермерском хозяйстве благодаря применению новых технологий урожайность пшеницы возрасла на 3 ц с 1 га. в результате было собрано не 190 ц пшеницы, как в предшествующем году, а 198 ц, хотя под пшеницу отвели на 1 га меньше. какая площадь была отведена в хозяйстве под пшеницу в эти годы?

Answer 1

Calculation of the Area of Wheat Cultivation

To calculate the area of wheat cultivation in the given years, we can use the information provided about the increase in wheat yield per hectare.

In the previous year, the yield of wheat was 190 centners (1 centner = 100 kilograms) from an unknown area. In the current year, the yield increased by 3 centners per hectare, resulting in a total yield of 198 centners. However, the area allocated for wheat cultivation was 1 hectare less than the previous year.

Let's assume the area of wheat cultivation in the previous year was A hectares. Therefore, the area of wheat cultivation in the current year would be A - 1 hectares.

To find the value of A, we can set up the following equation:

190A = 198(A - 1)

Simplifying the equation:

190A = 198A - 198

8A = 198

A = 198 / 8

A = 24.75 hectares

Therefore, the area allocated for wheat cultivation in these years was approximately 24.75 hectares.

Please note that the given information does not provide the exact values for the area of wheat cultivation in each year. The calculation above is based on the assumption that the increase in yield per hectare is consistent across the entire area of wheat cultivation.
