Question

Периметр параллелограмма равен 46 см. Найдите стороны параллелограмма, если одна сторона на 5 см меньше другой. В ответ запишите длину большей стороны. Ответ дайте в сантиметрах.

Answer 1

Ответ:

х+х+х+5+х+5=46

4х=46-10

4х=36

х=9

х+5=14 см

ответ 14 см

Answer 2

Ответ:

Пусть меньшая сторона х тогда большая будет х+5

Составим уравнение:

(х+х+5)•2=46

4х+10=46

4х=36

х=9

Тогда меньшая сторона равна 9 см а большая 9+5=14 см

Ответ : 14см

Answer 3

Finding the sides of a parallelogram

To find the sides of a parallelogram, we need to use the given information about the perimeter and the relationship between the sides.

Let's assume that one side of the parallelogram is x cm. According to the problem, the other side is 5 cm longer than the first side. Therefore, the length of the second side is (x + 5) cm.

The perimeter of a parallelogram is calculated by adding the lengths of all four sides. In this case, the perimeter is given as 46 cm.

Using the information above, we can set up the equation:

Perimeter = 2 * (Length of Side 1 + Length of Side 2)

46 = 2 * (x + (x + 5))

Simplifying the equation:

46 = 2 * (2x + 5)

Dividing both sides by 2:

23 = 2x + 5

Subtracting 5 from both sides:

18 = 2x

Dividing both sides by 2:

9 = x

Therefore, one side of the parallelogram is 9 cm. The other side, which is 5 cm longer, is (9 + 5) = 14 cm.

So, the length of the larger side of the parallelogram is 14 cm.
