Question

Периметр паралелограма дорівнює 36 дм . Знайдіть його сторони , якщо одна з них нв 2 дм менша від другої

Answer 1

Ответ:P = 2(a + b), де a і b — сторони паралелограма. 1) Менша сторона — x дм, більша сторона — (x + 2) дм. P = 2(x + x + 2) = 4x + 4. За умовою 4x + 4 = 36, 4x = 32, x = 8.

Answer 2

Perimeter of a Parallelogram

To find the sides of a parallelogram when the perimeter is given, we need to use the formula for the perimeter of a parallelogram. The formula for the perimeter of a parallelogram is:

Perimeter = 2(a + b)

Where: - a is the length of one side of the parallelogram - b is the length of the adjacent side of the parallelogram

In this case, we are given that the perimeter of the parallelogram is 36 dm and that one side is 2 dm less than the other side.

Let's assume that the length of one side of the parallelogram is x dm. According to the given information, the length of the other side would be x + 2 dm.

Using the formula for the perimeter, we can set up the equation:

36 = 2(x + (x + 2))

Simplifying the equation:

36 = 2(2x + 2)

36 = 4x + 4

Subtracting 4 from both sides:

32 = 4x

Dividing both sides by 4:

x = 8

Therefore, the length of one side of the parallelogram is 8 dm, and the length of the other side is 8 + 2 = 10 dm.

So, the sides of the parallelogram are 8 dm and 10 dm.
