Question

Одна из сторон параллелограмма в 3 раза меньше ,а его периметр 72см.найдите стороны параллелограмма.

Answer 1

2(x+3x)=72
4x=36
x1=9
x2=27

Answer 2

Given Information:

We are given that one side of a parallelogram is 3 times smaller than the other side, and the perimeter of the parallelogram is 72 cm.

Solution:

Let's assume that the longer side of the parallelogram is represented by x cm. According to the given information, the shorter side will be 3x cm.

The perimeter of a parallelogram is calculated by adding the lengths of all four sides. In this case, we have two sides of length x cm and two sides of length 3x cm.

The perimeter of the parallelogram is given as 72 cm. Therefore, we can set up the equation:

2x + 2(3x) = 72

Simplifying the equation:

2x + 6x = 72

8x = 72

Dividing both sides of the equation by 8:

x = 9

Now that we have the value of x, we can find the lengths of both sides of the parallelogram.

The longer side, represented by x, is 9 cm.

The shorter side, represented by 3x, is 3 * 9 = 27 cm.

Therefore, the sides of the parallelogram are 9 cm and 27 cm.

Answer:

The longer side of the parallelogram is 9 cm, and the shorter side is 27 cm.
