Question

Площадь классной доски прямоугольной формы 288дм а ее длина 24дм найди ширинудоски.составь обратные задачи и реши их.

Answer 1

288/24=12 дм ширина
обратные задачи цифры те же только неизвестные меняешь
обратная найти площадь доски если известны ее дина 24 дм и ширина 12 дм
24*12=288 дм квадратных
площадь 288дм ширина 12 дм, чему равна длина

Answer 2

Finding the Width of the Classroom Board

To find the width of the rectangular classroom board, we can use the formula for the area of a rectangle: Area = Length × Width.

Given that the area of the board is 288 dm² and the length is 24 dm, we can substitute these values into the formula and solve for the width.

Let's calculate it step by step:

1. Substitute the given values into the formula: - Area = 288 dm² - Length = 24 dm

2. Rearrange the formula to solve for the width: - Area = Length × Width - Width = Area / Length

3. Calculate the width: - Width = 288 dm² / 24 dm - Width = 12 dm

Therefore, the width of the classroom board is 12 dm.

Solving Reverse Problems

Now, let's create some reverse problems based on the given information and solve them.

1. Reverse Problem 1: - Question: If the length of a rectangular board is 12 dm and the width is 6 dm, what is the area of the board? - Solution: To find the area, we can use the formula Area = Length × Width. - Area = 12 dm × 6 dm - Area = 72 dm² - Answer: The area of the board is 72 dm².

2. Reverse Problem 2: - Question: If the area of a rectangular board is 96 dm² and the width is 8 dm, what is the length of the board? - Solution: To find the length, we can rearrange the formula Area = Length × Width and solve for Length. - Area = Length × Width - Length = Area / Width - Length = 96 dm² / 8 dm - Length = 12 dm - Answer: The length of the board is 12 dm.

These are just a couple of examples of reverse problems that can be solved using the given information. You can create more reverse problems by changing the values of length, width, and area and applying the appropriate formulas.
