Question

1. Одна зі сторін паралелограма удвічі менша, ніж інша, а його периметр дорівнює 36 см. Знайти більшу сторону паралелограма.

Answer 1

2X = 12

Пошаговое объяснение:

Нехай одна сторона дорівнює Х cм, тоді друга дорівнює 2Х. Протилежні сторони паралелограма рівні. Периметр – сума довжин всіх сторін.

X + 2X + X + 2X = 36

6X = 36

X = 6

2X = 12

Answer 2

Ответ:

(2x+x)×2=36

3x=36÷2

3x=18

x=6

6×2=12

Відповідь:12 см

Answer 3

Finding the larger side of a parallelogram

To find the larger side of a parallelogram, we need to use the information given about the perimeter of the parallelogram. Let's denote the lengths of the sides of the parallelogram as a and b.

According to the given information, one side of the parallelogram is twice as small as the other side. Let's assume that the smaller side is a and the larger side is b. Therefore, we can write the equation:

a = (1/2)b (Equation 1)

The perimeter of a parallelogram is calculated by adding the lengths of all four sides. In this case, the perimeter is given as 36 cm. Since opposite sides of a parallelogram are equal in length, we can write the equation:

2a + 2b = 36 (Equation 2)

Now, we can solve this system of equations to find the values of a and b.

Substituting Equation 1 into Equation 2, we get:

2(1/2)b + 2b = 36

Simplifying the equation:

b + 2b = 36

3b = 36

Dividing both sides by 3:

b = 12

Now that we have found the value of b, we can substitute it back into Equation 1 to find the value of a:

a = (1/2)b = (1/2)(12) = 6

Therefore, the larger side of the parallelogram is 12 cm.
