Question

Начерти план участка прямоугольной формы со сторонами 4м и 9м изображая 1м² одной клеткой .покажи на плане что огурцами занято 12м² а помидорами на 4м²больше чем огурцами . Сколько квадратных метров участка остались свабодными

Answer 1

Наверно
4м-400см
9м-900см
4*3=12
12+4=16
4*9=36
12+16=28
36-28=8 
ответ: свободной земли 8м²

Answer 2

Drawing the Plot

To draw the plot, we'll start by representing the rectangular plot with sides of 4m and 9m. Each square meter will be represented by one cell.

The plot will be divided into cells, with each cell representing 1m². We'll then mark 12 cells for the area occupied by cucumbers and 16 cells for the area occupied by tomatoes.

Representing the Plot

``` 1 2 3 4 5 6 7 8 9 1| | | | | | | | | | 2| | | | | | | | | | 3| | | | | | | | | | 4| | | | | | | | | | ```

Marking the Area for Cucumbers

We'll mark 12 cells to represent the 12m² area occupied by cucumbers.

  1   2   3   4   5   6   7   8   9
1| X | X | X | X |   |   |   |   |   |
2| X | X | X | X |   |   |   |   |   |
3| X | X | X | X |   |   |   |   |   |
4| X | X | X | X |   |   |   |   |   |

Marking the Area for Tomatoes

We'll mark 16 cells to represent the 16m² area occupied by tomatoes.

  1   2   3   4   5   6   7   8   9
1| X | X | X | X |   |   |   |   |   |
2| X | X | X | X |   |   |   |   |   |
3| X | X | X | X |   |   |   |   |   |
4| X | X | X | X | X | X | X | X |   |

Calculating the Remaining Area

To find the remaining area, we'll calculate the total area of the plot and subtract the areas occupied by cucumbers and tomatoes.

Total Area: Total area = length × width Total area = 4m × 9m Total area = 36m²

Area Occupied by Cucumbers: Area occupied by cucumbers = 12m²

Area Occupied by Tomatoes: Area occupied by tomatoes = 16m²

Remaining Area: Remaining area = Total area - (Area occupied by cucumbers + Area occupied by tomatoes) Remaining area = 36m² - (12m² + 16m²) Remaining area = 36m² - 28m² Remaining area = 8m²

Answer: The remaining area of the plot is 8 square meters.
