Question

В равнобедренной трапеции Боковая сторона равна 9 см а средняя линия 11 см Найдите периметр трапеции пожалуйста срочно с чертежом ​

Answer 1

периметр-это сумма всех сторон

значит 9+9+9+11

или 9×3+11

будет 38см

Р=38 см

Объяснение:

прости, но я могу ошибаться

Answer 2

Perimeter of an Isosceles Trapezoid

To find the perimeter of an isosceles trapezoid, we need to know the lengths of the two parallel sides (the bases) and the lengths of the two non-parallel sides (the legs).

In this case, we are given that one of the legs (the lateral side) is 9 cm long, and the length of the median line (the average of the two bases) is 11 cm.

To find the perimeter, we can use the formula:

Perimeter = sum of all sides

In an isosceles trapezoid, the two bases are equal in length. Let's assume the length of each base is 'b' cm.

The perimeter can be calculated as follows:

Perimeter = b + b + 9 + 11

Simplifying the equation, we get:

Perimeter = 2b + 20

Now, we need to find the value of 'b' to calculate the perimeter.

Unfortunately, the given information does not provide enough data to determine the value of 'b' or draw a diagram of the trapezoid. Therefore, we cannot provide a specific numerical answer or a diagram in this case.

Please provide additional information or clarify the question if you need further assistance.
