Question

периметр паралелограмма равен 30 см .Найдите стороны параллелограмма если одна из сторон в 4 раза больше других​

Answer 1

Ответ:a=3, b=12

Объяснение:

Пусть одна сторона параллелограмма равна х, Тогда вторая сторона параллелограмма равна 4х .

Периметр параллелограмма P=2(a+b)

P=30

a=x

b=4x

2(x+4x)=30

10x=30

x=3

a=3

b=4*3=12

Answer 2

Perimeter of a Parallelogram

To find the sides of a parallelogram when one side is 4 times larger than the other sides, we need to use the formula for the perimeter of a parallelogram.

The perimeter of a parallelogram is calculated by adding the lengths of all four sides. In this case, we are given that the perimeter is equal to 30 cm.

Let's assume that the length of one of the smaller sides is "x" cm. Since one side is 4 times larger than the other sides, the length of the larger side would be "4x" cm.

To find the perimeter, we can add the lengths of all four sides:

Perimeter = x + x + 4x + 4x = 10x

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

10x = 30

Solving for "x":

x = 30 / 10 = 3 cm

Therefore, the length of one of the smaller sides is 3 cm, and the length of the larger side is 4 times that, which is 12 cm.

So, the sides of the parallelogram are: - One of the smaller sides: 3 cm - The other smaller side: 3 cm - One of the larger sides: 12 cm - The other larger side: 12 cm
