Question

Скажите пожалуйста. Пириметор прямоугольника равен 88см. Найти площадь,если его ширина равна 18 дм.

Answer 1

Ответ: Пошаговое объяснение: х- ширина, х+18 - длина, P=2а+2b(где а -ширина, b - длина)

Подставляем:

88=2х+2(х+18);

88=2х+2х+36;

88-36=4х;

52=4х;

13=х. (это мы нашли ширину) 13+18=31 - длина

S=13*31=403(дм^2)

Answer 2

Ответ:

Пошаговое объяснение:

Ширина не может быть 18дм тк 180см и больше Р,а если 18 см то

88-2×18=52см сумма 2х длин

52÷2=26см длина

18×26=468см² площадь

Answer 3

Problem Statement

You are given the perimeter of a rectangle, which is 88 cm, and the width of the rectangle, which is 18 dm. You need to find the area of the rectangle.

Solution

To find the area of a rectangle, we need to know the length and width of the rectangle. In this case, we are given the width, which is 18 dm. However, we need to convert the width to cm to match the units of the perimeter.

To convert dm to cm, we multiply the value by 10, since there are 10 cm in 1 dm. Therefore, the width of the rectangle in cm is 18 dm * 10 cm/dm = 180 cm.

Now, let's denote the length of the rectangle as L. We know that the perimeter of a rectangle is given by the formula: perimeter = 2 * (length + width).

Substituting the given values, we have: 88 cm = 2 * (L + 180 cm)

To solve for L, we can simplify the equation: 44 cm = L + 180 cm

Now, let's isolate L by subtracting 180 cm from both sides of the equation: L = 44 cm - 180 cm L = -136 cm

However, a negative length does not make sense in this context. It is likely that there was an error in the given information or in the calculations.

Therefore, it is not possible to find the area of the rectangle with the given information.

Please double-check the values provided and ensure that they are accurate.
