Question

Чему равен периметр четырехугольника, у которого две стороны имеют одинаковую длину 23,46 дм, длина третьей стороны 18,21 м, четвертая сторона на m дм короче третьей стороны?

Answer 1

Переведем длину в одинаковые единицы.
18,21 м = 182,1 м.
a= b = 23.46,  c =182.1,  d = c-m.
Периметр - это сумма сторон.
Р= a+b+c+d = 2*23,46 + 182,1 +(182,1-m)
Раскрываем скобки и упрощаем.
Р= 2*(23,46+182,1)-m =2*205,56 -m = 411,12 -m - ОТВЕТ где m - в дм.

Answer 2

Perimeter of a Quadrilateral

To find the perimeter of a quadrilateral, we need to add up the lengths of all four sides. In this case, we are given that two sides have a length of 23.46 dm, the third side has a length of 18.21 m, and the fourth side is m dm shorter than the third side.

Let's calculate the perimeter step by step:

1. Convert the length of the third side from meters to decimeters: - 18.21 m = 182.1 dm

2. Determine the length of the fourth side: - The fourth side is m dm shorter than the third side, so it can be expressed as (182.1 - m) dm.

3. Calculate the perimeter: - Perimeter = (23.46 + 23.46 + 182.1 + (182.1 - m)) dm

Now, we can simplify the expression and find the perimeter.

Perimeter = 2 * 23.46 dm + 2 * 182.1 dm - m dm

Let's calculate the perimeter using the given values.

Perimeter = 2 * 23.46 dm + 2 * 182.1 dm - m dm

Perimeter = 46.92 dm + 364.2 dm - m dm

Perimeter = 411.12 dm - m dm

Therefore, the perimeter of the quadrilateral is 411.12 dm - m dm.

Please note that the value of 'm' is not provided in the question, so we cannot determine the exact perimeter without knowing the value of 'm'.
