Question

Периметр прямоугольного участка 20,4 м. Длина 6,4. Найдите площадь участка

Answer 1

1)20,4-6,4-6,4=7,6(ширина)
2)Площадь=длину умножить на ширину
S=6.4*7.6=48.64
Ответ:48.64

Answer 2

Calculation of the Area of a Rectangular Plot

To find the area of a rectangular plot, we need to know the length and width of the plot. In this case, the length of the plot is given as 6.4 meters, and the perimeter is given as 20.4 meters.

To calculate the width of the plot, we can use the formula for the perimeter of a rectangle:

Perimeter of a rectangle = 2 * (length + width) Substituting the given values, we have:

20.4 = 2 * (6.4 + width)

Simplifying the equation:

20.4 = 12.8 + 2 * width

Rearranging the equation:

2 * width = 20.4 - 12.8

2 * width = 7.6

width = 7.6 / 2

width = 3.8 meters

Now that we have the length and width of the plot, we can calculate the area using the formula:

Area of a rectangle = length * width

Substituting the given values:

Area = 6.4 * 3.8

Area = 24.32 square meters

Therefore, the area of the rectangular plot is 24.32 square meters.
