Скатерть, которая имеет форму прямоугольника со сторонами 2 м и 3 м ,со всех сторон обшивают
тесьмой.Хватит ли для этого 9 м тесьмы? Подчеркни правильный ответ: да, нет. Ответ поясни вычислениями.

Ответы на вопрос

2) 10 - 9 = 1 ( m )
ответ не хватит одного метра



10-9=1м не хватает до полной обшивки



Calculation of the Required Trim Length
To determine whether 9 meters of trim will be sufficient to cover a rectangular tablecloth with dimensions 2 meters by 3 meters, we need to calculate the total length of the tablecloth's edges.
The formula to calculate the perimeter of a rectangle is:
Perimeter = 2 * (Length + Width)
In this case, the length of the tablecloth is 2 meters and the width is 3 meters. Plugging these values into the formula, we get:
Perimeter = 2 * (2 + 3) = 2 * 5 = 10 meters
Therefore, the total length of the tablecloth's edges is 10 meters.
Determining if 9 Meters of Trim is Sufficient
Now that we know the total length of the tablecloth's edges is 10 meters, we can compare it to the length of the trim, which is 9 meters.
If the length of the trim is equal to or greater than the total length of the tablecloth's edges, then it will be sufficient to cover the tablecloth. Otherwise, it will not be enough.
In this case, since the length of the trim is 9 meters and the total length of the tablecloth's edges is 10 meters, we can conclude that 9 meters of trim will not be enough to cover the tablecloth.
Conclusion
In summary, if the tablecloth has dimensions of 2 meters by 3 meters and the trim available is 9 meters long, it will not be sufficient to cover the tablecloth. The total length of the tablecloth's edges is 10 meters, which is greater than the length of the trim. Therefore, the correct answer is no.
