Question

1 із сторін паралелограма на 12 м більше за 2-у А його периметр = 70 сантиметрів знайти сторони паралелограма

Answer 1

Ответ:

Р=2а+2в=2х+2(х+12)

2х+2(х+12)=70

2х+2х+24=70

4х=70-24

4х=46

х=46÷4

х=11.5

одна сторона дорівнює х. х=11.5см

друга сторона дорівнює х+12=11.5+12=23.5см

Answer 2

Finding the sides of a parallelogram

To find the sides of a parallelogram, we need to use the given information about the difference in length between two sides and the perimeter of the parallelogram.

Let's denote the length of one side of the parallelogram as A. According to the problem, one of the sides is 12 meters longer than twice the length of side A. So, the length of the other side can be expressed as 2A + 12.

The perimeter of a parallelogram is the sum of all its sides. In this case, the perimeter is given as 70 centimeters.

To find the sides of the parallelogram, we can set up an equation using the given information:

A + (2A + 12) + A + (2A + 12) = 70

Simplifying the equation:

6A + 24 = 70

Subtracting 24 from both sides:

6A = 46

Dividing both sides by 6:

A = 7.67

Now that we have the value of A, we can substitute it back into the expression for the other side:

2A + 12 = 2(7.67) + 12 = 27.34

Therefore, the sides of the parallelogram are approximately 7.67 centimeters and 27.34 centimeters.

Please note that the units used in the problem are inconsistent (meters for the difference in length and centimeters for the perimeter). I assumed that the sides of the parallelogram are measured in centimeters to match the given perimeter.
