Question

Одна из сторон параллелограмма в 4 раза больше другой а его пириметр равен 30м.чему равны стороны параллелограмма

Answer 1

Периметр равен сумме всех сторон, так как это параллелограмм, то можно вычислить его по формуле P=2(AB+СD) ( где AB и CD - смежные стороны) 
Пусть AB=x, тогда CD=4х. 
2(х+4х)=30
2х+8х=30
10х=30
х=3-одна сторона
3*4=12- другая сторона
Ответ: 3 и 12 

Answer 2

Пусть одна сторона х см Другая-4x cм.Тогда х+4х=15 х=3 - одна сторона 3*4=12 см- другая.

Answer 3

Problem Analysis

We are given that one side of a parallelogram is 4 times larger than the other side, and the perimeter of the parallelogram is 30 meters. We need to find the lengths of the sides of the parallelogram.

Solution

Let's assume that the shorter side of the parallelogram is represented by the variable x. According to the problem, the longer side is 4 times larger, so it can be represented by the variable 4x.

The perimeter of a parallelogram is given by the formula: P = 2(a + b), where P is the perimeter, a and b are the lengths of the adjacent sides.

In this case, the perimeter is given as 30 meters, so we can write the equation as: 30 = 2(x + 4x).

Simplifying the equation, we get: 30 = 2(5x).

Dividing both sides by 2, we have: 15 = 5x.

Solving for x, we find: x = 3.

Therefore, the shorter side of the parallelogram is 3 meters, and the longer side is 4 times larger, which is 12 meters.

Answer

The lengths of the sides of the parallelogram are 3 meters and 12 meters.
