Question

Стороны параллелограмма относятся как1:2 периметр равен30 см .Найдите стороны параллелограмма

Answer 1

10 и 5 вроде ну тип 10+10+5+5=30

Answer 2

Допустим, одна сторона х, тогда
Р=х+2х+х+2х=30
6х=30
х=30/6
х=5 см одна сторона
2*5=10см вторая сторона

или
Р=2(а+в)
а+в=Р/2=30/2=15см
так как отношение 1:2, то имеем 3 части
15/3=5см одна часть и значит одна сторона, а вторая сторона 2*5=10см

Answer 3

Finding the Sides of a Parallelogram

To find the sides of a parallelogram when the ratio of the sides is given and the perimeter is known, we can follow these steps:

1. Let's assume the ratio of the sides of the parallelogram is 1:2. 2. Let's assign variables to the lengths of the sides. Let's call the shorter side "x" and the longer side "2x". 3. The perimeter of a parallelogram is the sum of all its sides. In this case, the perimeter is given as 30 cm. 4. We can set up an equation to represent the perimeter: x + 2x + x + 2x = 30. 5. Simplifying the equation, we get 6x = 30. 6. Dividing both sides of the equation by 6, we find that x = 5. 7. Therefore, the shorter side of the parallelogram is 5 cm, and the longer side is 2 times that, which is 10 cm.

So, the sides of the parallelogram are 5 cm and 10 cm.
