Question

Огород имеет форму прямоугольника длина которого 8 м.,ширина 2,5 на 0.4 всей площади огорода посажена морковь на остальной лук и чеснок причём луком засажена площадь в 4 раза большая чем чесноком.Какая площадь засажена морковью,луком и чесноком в отдельности?

Answer 1

Дано:
Ширина 2,5
Длина 8
0,4 засажено морковью
Лука в 4 раза больше, чем чеснока
Какая площадь засажена морковью,луком и чесноком в отдельности?

Решение:
1) 8*2,5 = 20 м2 площадь огорода
2)20*0,4 = 8 м2 занимает морковь
3)20 - 8 = 12 м2 занимает лук и чеснок
4)х+4х = 12
5х=12
х=2,4 м2 засажено чесноком
4)12-2,4 = 9,6 м2 засажено луком

ответ: 8 м2, 9,6 м2, 2,4 м2

Answer 2

Calculation of Garden Area

The garden has a rectangular shape with a length of 8 meters and a width of 2.5 meters. To calculate the area of the garden, we can use the formula: Area = Length x Width.

Using this formula, the area of the garden is: Area = 8 meters x 2.5 meters = 20 square meters. [[1]]

Calculation of Onion and Garlic Areas

According to the given information, the area planted with onions is 4 times larger than the area planted with garlic. Let's assume the area planted with garlic is represented by 'x' square meters. Therefore, the area planted with onions is 4 times 'x', or 4x square meters.

The total area of the garden is 20 square meters, and the area planted with garlic is 'x' square meters. So, the area planted with onions is 4x square meters.

To find the value of 'x', we can set up an equation: x + 4x = 20

Combining like terms: 5x = 20

Solving for 'x': x = 20 / 5 = 4 square meters.

Therefore, the area planted with garlic is 4 square meters, and the area planted with onions is 4 times that, or 16 square meters. [[2]]

Calculation of Carrot Area

The remaining area of the garden is planted with carrots. To find the area planted with carrots, we subtract the combined area of onions and garlic from the total area of the garden.

Total area of the garden = 20 square meters Area planted with onions = 16 square meters Area planted with garlic = 4 square meters

Area planted with carrots = Total area - (Area planted with onions + Area planted with garlic) Area planted with carrots = 20 square meters - (16 square meters + 4 square meters) Area planted with carrots = 20 square meters - 20 square meters Area planted with carrots = 0 square meters.

Therefore, the area planted with carrots is 0 square meters. [[3]]

Summary

To summarize, the areas planted with different vegetables in the garden are as follows: - Carrots: 0 square meters - Onions: 16 square meters - Garlic: 4 square meters.
