Question

Помогите срочно!!!Три бригады вырастили горох на площади 72целых 19 двадцатых га.Первая вторая бригады вырастили горох на площади 44 целых 3 четветых га.А вторая и третья на площади 52 целых 9 двадцатых. Найдите площадь каждого участка

Answer 1

1)72 и 19/20 - 44 и 3/4 = 72,95-44,75=28,2 га - площадь 3й бригады
2)72 и 19/20 - 52 и 9/20 = 72,95-52,45 = 20,5 га - площадь 1й бригады
3) 72,95 - 28,2 - 20,5 = 24,25 га - площадь 2й бригады

Answer 2

Calculation of the Areas

To find the area of each plot, we can use the given information and perform some calculations.

Let's denote the areas of the three plots as follows: - Area of the first plot: A1 - Area of the second plot: A2 - Area of the third plot: A3

From the given information, we have the following equations:

1. A1 + A2 + A3 = 72.19 hectares 2. A1 + A2 = 44.03 hectares 3. A2 + A3 = 52.45 hectares

To find the individual areas, we can solve these equations simultaneously.

Solving the Equations

Let's solve the equations using a method called substitution.

From equation 2, we can express A1 in terms of A2: A1 = 44.03 - A2

Substituting this value of A1 in equation 1, we get: (44.03 - A2) + A2 + A3 = 72.19

Simplifying the equation, we have: 44.03 + A3 = 72.19

From equation 3, we can express A3 in terms of A2: A3 = 52.45 - A2

Substituting this value of A3 in the simplified equation, we get: 44.03 + (52.45 - A2) = 72.19

Simplifying the equation further, we have: 96.48 - A2 = 72.19

Solving for A2, we find: A2 = 96.48 - 72.19 A2 = 24.29 hectares

Substituting this value of A2 in equation 2, we can find A1: A1 = 44.03 - A2 A1 = 44.03 - 24.29 A1 = 19.74 hectares

Substituting the values of A2 and A3 in equation 3, we can find A3: A3 = 52.45 - A2 A3 = 52.45 - 24.29 A3 = 28.16 hectares

Calculation Results

Based on the calculations, we have determined the following areas for each plot:

- Area of the first plot: 19.74 hectares - Area of the second plot: 24.29 hectares - Area of the third plot: 28.16 hectares

Please note that these values are approximate and rounded to two decimal places.

I hope this helps! Let me know if you have any further questions.
