Question

Площадь сквера прямоугольной формы 1000м(квадратных).Вдоль ограды сквера высажены цветы.Длинная сторона сквера 40м.Вычисли длину цветника

Answer 1

Площадь=а*в
а=40 м
в-?
40*х=1000
х=1000:40
х=25 длинна короткой стороны
Периметр=2а+2в=2*40+2*25=80+50=130-длина цветника

Answer 2

Calculation of the Length of the Flowerbed

To calculate the length of the flowerbed along the fence of a rectangular square with an area of 1000 square meters and a long side of 40 meters, we can use the formula for the perimeter of a rectangle.

The formula for the perimeter of a rectangle is given by:

Perimeter = 2 * (Length + Width)

In this case, we know that the area of the square is 1000 square meters, and the long side is 40 meters. Since the square is rectangular, the length and width are equal.

Let's assume the length of the square is 'x' meters. Then, the width of the square will also be 'x' meters.

We can set up an equation using the given information:

x * x = 1000 (since the area of the square is 1000 square meters)

Simplifying the equation, we have:

x^2 = 1000

To find the value of 'x', we can take the square root of both sides of the equation:

x = √1000

Evaluating the square root, we find:

x ≈ 31.62

Therefore, the length of the square is approximately 31.62 meters.

Now, we can calculate the length of the flowerbed along the fence. Since the flowerbed is planted along the perimeter of the square, the length of the flowerbed will be equal to the perimeter of the square.

Using the formula for the perimeter of a rectangle, we have:

Perimeter = 2 * (Length + Width)

Substituting the values we have:

Perimeter = 2 * (31.62 + 31.62)

Calculating the perimeter, we find:

Perimeter ≈ 126.48 meters

Therefore, the length of the flowerbed along the fence is approximately 126.48 meters.

Please note that the calculations provided are approximate due to rounding.
