Question

Периметр параллелограмма равен 64 см одна,из его сторон равна 20 см . найдите длину оставшихся сторон

Answer 1

У параллелограмма противоположные стороны равны ,значит 2 стороны по 20 см. 20+20= 40, 64 - 40= 24, 24: 2= 12. ответ 12, 12, 20, 20

Answer 2

Perimeter of a Parallelogram

To find the length of the remaining sides of a parallelogram, we need to know the length of one side and the perimeter of the parallelogram. In this case, we are given that the perimeter of the parallelogram is 64 cm and one side is 20 cm.

Let's denote the length of the remaining sides as a and b.

Solution

The perimeter of a parallelogram is given by the formula: P = 2(a + b), where P is the perimeter, and a and b are the lengths of the sides.

Given that the perimeter is 64 cm, we can write the equation as: 64 = 2(20 + a + b).

Simplifying the equation, we get: 32 = 20 + a + b.

To find the lengths of the remaining sides, we need another equation. Unfortunately, the given information is not sufficient to determine the exact lengths of the remaining sides.

Therefore, we cannot determine the lengths of the remaining sides of the parallelogram with the given information.

Please provide additional information if available, such as angles or ratios, to further solve the problem.

I hope this helps! Let me know if you have any further questions.
