Question

С двух участков земли общей площадью 20 кв.м. собрали огурцы.С первого участка собрали 330 кг,а со второго 270кг.Какой была площадь каждого участка,если масса собранного урожая с каждого квадратного метра была одинаковой.

Answer 1

1. 330+270=600 кг огурцов собрали
2. 600/20=30кг с 1 квм
3. 330/30=11 кв м площадь первого участка
4. 20-11=9 кв м площадь второго (ну или 280/30=9)

Answer 2

Problem Analysis

We are given two plots of land with a total area of 20 square meters. The cucumbers harvested from each square meter of land have the same weight. We need to determine the area of each plot if the total weight of cucumbers harvested from each plot is 330 kg and 270 kg, respectively.

Solution

Let's assume the area of the first plot is x square meters and the area of the second plot is y square meters. We can set up the following equations based on the given information:

1. The total area of the two plots is 20 square meters: x + y = 20. 2. The total weight of cucumbers harvested from the first plot is 330 kg: 330 kg = 330 kg/m^2 * x. 3. The total weight of cucumbers harvested from the second plot is 270 kg: 270 kg = 270 kg/m^2 * y.

To solve this system of equations, we can use substitution or elimination. Let's use substitution:

From equation 1, we have x = 20 - y. Substituting this value into equations 2 and 3, we get:

330 kg = 330 kg/m^2 * (20 - y)

270 kg = 270 kg/m^2 * y

Now we can solve these equations to find the values of x and y.

Calculation

Let's solve the equations:

330 kg = 330 kg/m^2 * (20 - y)

Simplifying the equation:

330 kg = 6600 kg - 330 kg/m^2 * y

Rearranging the equation:

330 kg/m^2 * y = 6600 kg - 330 kg

330 kg/m^2 * y = 6270 kg

Dividing both sides by 330 kg/m^2:

y = 6270 kg / 330 kg/m^2

y = 19 m^2

Now, substituting the value of y into equation 1:

x + 19 m^2 = 20 m^2

Subtracting 19 m^2 from both sides:

x = 1 m^2

Therefore, the area of the first plot is 1 square meter and the area of the second plot is 19 square meters.

Answer

The area of the first plot is 1 square meter and the area of the second plot is 19 square meters.
