Question

В рыбном хозяйстве в одном пруду вырастили по 7 кг карпа на 1 квадратный метр площади пруда и получили 67 200 кг рыбы, а в другом пруду - по 8 кг карпа на 1 квадратный метр площади и получили 61 600 кг рыбы. на сколько квадратных метров площадь одного пруда больше площади другого

Answer 1

67200:7-61600:8=9600-7700=1900(м2)
Ответ: на 1900 м2 площадь одного пруда больше пощади другого

Answer 2

67200/(7*1)=9600 кв.м.
61600/(8*1)=7700 кв.м
9600-7700=1900 кв.м
Ответ: на 1900 кв.м.

Answer 3

Calculation of Pond Areas

To determine the difference in the pond areas, we can set up a proportion based on the information provided. Let's assume the area of the first pond is x square meters, and the area of the second pond is y square meters.

According to the given information, in the first pond, 7 kg of carp were grown per 1 square meter, resulting in a total of 67,200 kg of fish. Therefore, we can set up the following equation:

7 kg/m^2 * x m^2 = 67,200 kg

Similarly, in the second pond, 8 kg of carp were grown per 1 square meter, resulting in a total of 61,600 kg of fish. We can set up the following equation for the second pond:

8 kg/m^2 * y m^2 = 61,600 kg

Solving the Equations

To find the values of x and y, we can solve the system of equations:

7x = 67,200

8y = 61,600

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

x = 9,600

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

y = 7,700

Calculation of the Difference in Pond Areas

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

x - y = 9,600 - 7,700 = 1,900

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

Please note that the calculations are based on the information provided and the assumption that the growth rate of carp is consistent throughout the entire pond area.
