Question

Садовник должен оградить участок земли длиной 4 м и шириной 2 м. Сколько метров сетки потребуется? Если для орошения земли используется 101 литр воды на 1 м², то сколько литров воды нужно от дедушки для орошения этой земли? дайте пожалуйста правильный ответ. дам 26 балла!

Answer 1

Ответ:

1) 12м

2) Площа S=ab, поэтому S=4*2=8

и поэтому нужно 808 литров получается

Answer 2

Ответ:P=4+2·2= 12м

ответ: 12 метров

2) S= 4·2= 8м

8·101= 808л

ответ: 808 литров

Answer 3

Calculation of the Required Length of Fence

To calculate the length of the fence needed to enclose a rectangular plot of land, we can use the formula:

Perimeter = 2 * (Length + Width)

Given that the length of the plot is 4 meters and the width is 2 meters, we can substitute these values into the formula:

Perimeter = 2 * (4 + 2) = 2 * 6 = 12 meters

Therefore, the gardener will need 12 meters of fencing to enclose the plot of land.

Calculation of the Required Amount of Water for Irrigation

To calculate the amount of water needed for irrigation, we need to know the area of the land and the water consumption per square meter.

The area of the land can be calculated using the formula:

Area = Length * Width

Substituting the given values:

Area = 4 * 2 = 8 square meters

Given that the water consumption is 101 liters per square meter, we can calculate the total amount of water needed:

Total Water Consumption = Area * Water Consumption per Square Meter

Total Water Consumption = 8 * 101 = 808 liters

Therefore, your grandfather will need 808 liters of water to irrigate this piece of land. I hope this helps! Let me know if you have any further questions.
