Question

Площадь трех участков равна 833 га площадь второго участка составляет 0,4 площади первого участка,а площадь третьего участка на 17 га больше площади первого. Какова площадь каждого участка. подсказка решать надо уравнением

Answer 1

Х- площадь первого
0,4х -площадь второго
х+17 площать третьего
По условию задачи площадь трёх 833 га. составляем уравнение
х+0,4х+х+17=833
2,4х=816
х=340 га- первого
340*0,4=136 га второго
340+17=357 га третьего

удачи!

Answer 2

Problem Analysis

We are given three plots of land, and we need to find the area of each plot. The total area of the three plots is 833 hectares. The area of the second plot is 0.4 times the area of the first plot, and the area of the third plot is 17 hectares more than the area of the first plot.

Solution

Let's assume the area of the first plot is x hectares.

According to the given information: - The area of the second plot is 0.4 times the area of the first plot, so the area of the second plot is 0.4x hectares. - The area of the third plot is 17 hectares more than the area of the first plot, so the area of the third plot is x + 17 hectares.

We know that the total area of the three plots is 833 hectares. Therefore, we can write the equation:

x + 0.4x + (x + 17) = 833

Simplifying the equation: 2.4x + 17 = 833

Subtracting 17 from both sides: 2.4x = 816

Dividing both sides by 2.4: x = 340

So, the area of the first plot is 340 hectares.

Using this value, we can find the area of the second plot: 0.4x = 0.4 * 340 = 136 hectares

And the area of the third plot: x + 17 = 340 + 17 = 357 hectares

Therefore, the area of each plot is as follows: - First plot: 340 hectares - Second plot: 136 hectares - Third plot: 357 hectares

Answer

The area of each plot is as follows: - First plot: 340 hectares - Second plot: 136 hectares - Third plot: 357 hectares
