Question

Периметр параллелограмма равен 40 см одна из его сторон на 5 см больше другой найдите стороны параллелограмма

Answer 1

Русь x=ab тогда да х +5=bc следовательно х+х+5+х+х+5=40; 4х +20=40;4х=20;х=20/4=5 ab=5;bc=cd=10:cd=5

Answer 2

Р- периметр
Р/2=20
Пусть одна сторона будет Х,а вторая (Х+5)
Х+Х+5=20
2Х=15
Х=7,5(ширина)
Длина=7,5+5=12,5

Answer 3

Perimeter of a Parallelogram

To find the sides of a parallelogram when the perimeter is given, we need to use the information provided. Let's break down the problem step by step.

Given: - Perimeter of the parallelogram = 40 cm - One side of the parallelogram is 5 cm longer than the other side

To find the sides of the parallelogram, we can set up an equation based on the perimeter.

Let's assume the shorter side of the parallelogram is x cm. Then the longer side would be (x + 5) cm.

The perimeter of a parallelogram is calculated by adding the lengths of all four sides. In this case, we have two equal pairs of sides, so we can simplify the equation:

Perimeter = 2 * (shorter side + longer side)

Substituting the given values:

40 cm = 2 * (x + (x + 5))

Now we can solve this equation to find the value of x, which represents the length of the shorter side.

40 cm = 2 * (2x + 5)

Dividing both sides by 2:

20 cm = 2x + 5

Subtracting 5 from both sides:

15 cm = 2x

Dividing both sides by 2:

x = 7.5 cm

Now that we have the value of x, we can find the lengths of both sides of the parallelogram.

The shorter side = x = 7.5 cm

The longer side = x + 5 = 7.5 cm + 5 cm = 12.5 cm

Therefore, the sides of the parallelogram are 7.5 cm and 12.5 cm.
