Question

Периметр прямоугольника 9,6 м. Длина в 1,4 раза больше ширины. Найдите площадь этого прямоугольника

Answer 1

Пусть х будет ширина, тогда длина 1,4х, периметр 9,6; 1)(х+1,4х)*2=9,6; 4,8х=9,6; х=2 м ширина прямоугольника; 2)2*1,4=2,8 м длина прям- как; 3)2*2,8=5,6м^2 площадь прямоугольника

Answer 2

Р=2(а+в)
ширина -х
длина - 1,4х
9,6=2(х+1,4х)
9,6=2*2,4х
9,6=4,8х
х=2  ширина
2*1,4=2,8   длина
S=а*в = 2*2,8=5,6

Answer 3

Calculating the Area of a Rectangle

To find the area of a rectangle, we can use the formula: Area = length * width. Given that the perimeter of the rectangle is 9.6 meters and the length is 1.4 times the width, we can calculate the area using the provided information.

Calculating the Width and Length

Let's denote the width of the rectangle as w and the length as 1.4w.

Finding the Perimeter

The perimeter of a rectangle can be calculated using the formula: Perimeter = 2 * (length + width).

From the provided snippets, we can see that the perimeter of a rectangle can also be calculated using the formula: P = a + b + c + d, where a, b, c, d are the sides of the rectangle.

From Source we have the formula for the perimeter: P = 2 * (a + b), where a and b are the length and width of the rectangle.

Using the Given Perimeter

The given perimeter is 9.6 meters. We can use this information to find the values of a and b.

Calculating the Area

Once we have the values of a and b, we can calculate the area using the formula: Area = a * b.

Conclusion

By following these steps, we can find the area of the given rectangle using the provided information.
