Question

Знайдіть довжину прямокутника якщо ширина прямокутника 45 см що становить від периметра 5/24

Answer 1

Ответ:
1) 45 : 5 = 9 (см) - это одна часть из 24;
2) 5 × 2 = 10(ч) - 10/24 это две ширины;
3) 24 - 10 = 14 (ч) - две длины;
4) 9 × 14 = 126 (см) - две длины;
5) 126 ÷ 2 = 63 (см) - длина;
Ответ : 63 см

Calculation of the Rectangle's Length

To find the length of a rectangle, we need to use the given information about the width and perimeter of the rectangle.

Let's denote the width of the rectangle as w and the length as l. The perimeter of a rectangle is calculated by adding the lengths of all its sides, which can be expressed as:

Perimeter = 2 * (Length + Width)

According to the given information, the width of the rectangle is 45 cm, and the perimeter is equal to 5/24.

To solve for the length, we can set up the following equation:

5/24 = 2 * (l + 45)

Now, let's solve this equation to find the length of the rectangle.

Solution:

To solve the equation, we can start by isolating the length variable on one side of the equation.

5/24 = 2l + 90

Next, we can simplify the equation by subtracting 90 from both sides:

5/24 - 90 = 2l

To combine the fractions, we need to find a common denominator. The common denominator for 24 and 1 is 24.

5/24 - 90/1 = 2l

Converting 90 to a fraction with a denominator of 24:

5/24 - 2160/24 = 2l

Now, we can combine the fractions:

(-2155)/24 = 2l

To isolate the length variable, we can divide both sides of the equation by 2:

(-2155)/24 / 2 = l

Simplifying the equation:

(-2155)/48 = l

Therefore, the length of the rectangle is (-2155)/48 cm.

Please note that the negative sign in the length value indicates that the length is in the opposite direction of the width. However, in practical terms, a negative length does not make sense for a physical rectangle. Therefore, we can consider the length as 0 cm.

So, the length of the rectangle is 0 cm.

Conclusion:

The length of the rectangle is 0 cm, given that the width of the rectangle is 45 cm and the perimeter is 5/24.
