Question

Периметр параллелограмма равен 32 см. Найдите стороны параллелограмма ( в см), если известно, что одна сторона в 3 раза больше другой

Answer 1

Пусть меньшие стороны равны х, большие- 3х, Р=2(х+3х)=8х=32,
х=32/8=4 см- меньшие, 3х=3*4=12 см-большие стороны параллелограмма

Answer 2

Perimeter of a Parallelogram

To find the sides of a parallelogram when the perimeter is given, we need to use the fact that opposite sides of a parallelogram are equal in length.

Let's assume that one side of the parallelogram is represented by the variable x. According to the given information, one side is 3 times larger than the other side. Therefore, the other side can be represented as x/3.

The perimeter of a parallelogram is the sum of all its sides. In this case, the perimeter is given as 32 cm. So we can set up the following equation:

2(x + x/3) = 32

Simplifying the equation:

2(4x/3) = 32

8x/3 = 32

To solve for x, we can multiply both sides of the equation by 3/8:

x = (32 * 3) / 8

x = 12

Now that we have the value of x, we can find the lengths of the sides of the parallelogram. One side is 12 cm, and the other side is 12/3 = 4 cm.

Therefore, the sides of the parallelogram are 12 cm and 4 cm.
