МАТЕМАТИКА В жизни 5 Реши задачу. «Когда я вырасту, то стану фермером», сказал Арман, Помоги ему решить задачу. Ширина поля – 250 м, а дли- на – на 150 м больше Одна пятая часть площа- ди поля засеяна овсом, а остальная часть — клеве- ром. На сколько квадрат- ных метров больше засе- Яно клевером, чем овсом? 79 Условия и решения и ответ​

Answer 1

Пошаговое объяснение:

Дано:

Ширина - 250 м.

Длина - ? м., на 150 метров больше чем ширина

Овес - 1/5 часть

Клевер - ?

Найти:

На сколько м2 больше засеяно клевером, чем овсом

Решение:

1) 250 + 150 = 400 м - длина

2) (250*400)/5 = 100000/5 = 20000 м2 - овес

3) 100000 - 20000 = 80000 м2 - клевер

4) 80000 - 20000 = 60000 м2

Ответ: На 60000 м2 больше.

Answer 2

Problem Analysis

The problem states that the width of the field is 250 meters and the length is 150 meters more than the width. One-fifth of the field is sown with oats, and the rest is sown with clover. We need to find the difference in square meters between the area sown with clover and the area sown with oats.

Solution

To solve this problem, we need to calculate the areas of the field sown with oats and clover separately and then find the difference between them.

Let's start by calculating the area of the field. The area of a rectangle is given by the formula: area = length × width.

Given that the width of the field is 250 meters, we can calculate the length as follows: length = width + 150.

Substituting the value of the width into the formula, we get: length = 250 + 150 = 400 meters.

Now we can calculate the area of the field: area = length × width = 400 × 250 = 100,000 square meters.

Next, we need to find the area sown with oats, which is one-fifth of the total area. To calculate this, we can use the formula: oats_area = (1/5) × total_area.

Substituting the values, we get: oats_area = (1/5) × 100,000 = 20,000 square meters.

Finally, we can find the area sown with clover by subtracting the area sown with oats from the total area: clover_area = total_area - oats_area.

Substituting the values, we get: clover_area = 100,000 - 20,000 = 80,000 square meters.

Therefore, the area sown with clover is 80,000 square meters.

To find the difference in square meters between the area sown with clover and the area sown with oats, we subtract the oats area from the clover area: difference = clover_area - oats_area.

Substituting the values, we get: difference = 80,000 - 20,000 = 60,000 square meters.

Therefore, the area sown with clover is 60,000 square meters more than the area sown with oats.

Answer

The area sown with clover is 60,000 square meters more than the area sown with oats.
