Answer 1

Х - одна часть.х +х+2х+2х=30
6х=30
х=5см
2*5=10 см

Answer 2

Given Information

We are given that the sides of a parallelogram are in a ratio of 1:2, and the perimeter of the parallelogram is 30 cm.

Solution

Let's assume that the shorter side of the parallelogram is x cm. Then, the longer side would be 2x cm, as per the given ratio.

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 2x cm.

So, the perimeter of the parallelogram can be expressed as: Perimeter = x + x + 2x + 2x = 6x

Given that the perimeter is 30 cm, we can set up the equation: 6x = 30

Solving this equation will give us the value of x, which we can then use to find the lengths of the sides.

Calculation

Let's solve the equation: 6x = 30

Dividing both sides of the equation by 6: x = 30/6 x = 5

Now that we have the value of x, we can find the lengths of the sides: Shorter side = x = 5 cm Longer side = 2x = 2 * 5 = 10 cm

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

Answer

The sides of the parallelogram are 5 cm and 10 cm.
