Question

Стороны паралеллограмма относятся как 1:2,а его периметр равен 30 см.найдите стороны паралеллограмма

Answer 1

Х ширина
2х длина
(х+2х)*2=30
3х=30:2
3х=15
х=5 см ширина
5*2=10 см длина

Answer 2

Let's denote the two sides of the parallelogram as "x" and "2x" since they are in the ratio 1:2.

The perimeter of a parallelogram is the sum of all its four sides. So, we can set up an equation to find the values of "x" and "2x" using the given information:

Perimeter = 30 cm Sum of all four sides = x + 2x + x + 2x = 6x

Now, equate the perimeter to 6x:

6x = 30

Now, solve for "x":

x = 30 / 6 x = 5

Now that we have the value of "x," we can find the two sides of the parallelogram:

One side = x = 5 cm Other side = 2x = 2 * 5 = 10 cm

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