Question

В рыбном хозяйстве в одном пруду вырастили 7 кг карпа на 1 м² площади пруда и получили 67 200 кг рыбы, а в другом пруду- 8 кг карпа на 1 м² площади и получили 61 600 кг рыбы. На сколько квадратных метров площадь одного пруда больше площади другого?Заранее спасибо, котаны =3

Answer 1

1) 67200:7=9600 (кв.м) - площадь 1 пруда
2) 61600:8=7700 (кв.м) - площадь 2 пруда
3) 9600-7700=1900 (кв.м)

Answer 2

1) 67 200 : 7 = 9 600 (м2) - площадь первого пруда
2) 61 600 : 8 = 7 700 (м2) - площадь второго пруда
3) 9 600 - 7 700 = 1 900 (м2) - разница
Ответ: площадь второго пруда больше площади первого на 1 900 м2.

Answer 3

Calculation of Pond Areas

To determine the difference in the areas of the two ponds, we can use the information provided about the fish yield and the weight of carp per square meter.

Let's denote the area of the first pond as A1 and the area of the second pond as A2.

According to the information given, in the first pond, 7 kg of carp were grown on 1 m² of pond area, resulting in a total yield of 67,200 kg of fish. Using this information, we can set up the following equation:

7 kg/m² × A1 = 67,200 kg

Similarly, in the second pond, 8 kg of carp were grown on 1 m² of pond area, resulting in a total yield of 61,600 kg of fish. This can be represented as:

8 kg/m² × A2 = 61,600 kg

Solving for Pond Areas

To find the difference in the areas of the two ponds, we need to solve the above equations simultaneously.

Dividing both sides of the first equation by 7 kg/m², we get:

A1 = 67,200 kg / 7 kg/m² = 9,600 m².

Dividing both sides of the second equation by 8 kg/m², we get:

A2 = 61,600 kg / 8 kg/m² = 7,700 m².

Difference in Pond Areas

To find the difference in the areas of the two ponds, we subtract the area of the second pond from the area of the first pond:

A1 - A2 = 9,600 m² - 7,700 m² = 1,900 m².

Therefore, the area of one pond is 1,900 square meters greater than the area of the other pond.
