Question

Периметр парал.64см одна з його сторин доривнюе 10см.знайти довжини решти сторин

Answer 1

Если подставить в формулу периметпериметра параллелограмма Р=2(а+б), то получится 64=2(10+б), 64=20+2б, 2б=44,б=22. Может быть так, но н точно не уверена

Answer 2

Problem Analysis

We are given that the perimeter of a parallelogram is 64 cm, and one of its sides is 10 cm long. We need to find the lengths of the remaining sides.

Solution

Let's denote the length of the side that is 10 cm long as 'a'. Since a parallelogram has opposite sides that are equal in length, the length of the opposite side will also be 'a'.

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

We are given that the perimeter is 64 cm, so we can write the equation as: 64 = 2(a + b).

Since one side is 10 cm long, we can substitute 'a' with 10 in the equation: 64 = 2(10 + b).

Simplifying the equation, we get: 64 = 20 + 2b.

Subtracting 20 from both sides, we have: 44 = 2b.

Dividing both sides by 2, we find: b = 22.

Therefore, the length of the remaining sides is 22 cm.

Answer

The lengths of the remaining sides of the parallelogram are 22 cm each.
