Question

ОТ прямоугольного участка площадью 1 га и шириной 40 м отделили участок площадью 28 соток. Каков периметр оставшегося участка?ПРОСЬБА С ОБЪЯСНЕНИЕМ!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

Участок земли имеет размеры 40 м на 10 000/40=250 м. Отделили 28 соток, т.е. отрезали участок 70м на 40 м. Следовательно остался 180 м на 40. А значит периметр = 180*2+40*2=440 м

Answer 2

Calculation of the Remaining Area

To find the perimeter of the remaining plot, we first need to calculate the area of the plot that was separated.

Given: - The total area of the rectangular plot is 1 hectare, which is equal to 10,000 square meters. - The width of the rectangular plot is 40 meters. - The area of the separated plot is 28 sotkas.

To calculate the area of the separated plot, we need to convert the area from sotkas to square meters.

1 sotka is equal to 100 square meters Therefore, the area of the separated plot is 28 sotkas * 100 square meters/sotka = 2800 square meters.

To find the area of the remaining plot, we subtract the area of the separated plot from the total area of the rectangular plot:

Remaining area = Total area - Separated area Remaining area = 10,000 square meters - 2800 square meters Remaining area = 7200 square meters

Calculation of the Perimeter

To find the perimeter of the remaining plot, we need to know the dimensions of the remaining plot. However, the problem statement does not provide the length or any other dimensions of the remaining plot. Therefore, it is not possible to calculate the exact perimeter of the remaining plot without additional information.

If we assume that the remaining plot is also rectangular, we can calculate the perimeter using the formula for the perimeter of a rectangle:

Perimeter = 2 * (Length + Width)

Since we only know the width of the original rectangular plot (40 meters), we cannot calculate the perimeter without knowing the length of the remaining plot.

Therefore, without additional information about the dimensions of the remaining plot, it is not possible to determine the exact perimeter of the remaining plot.

Please note that the above calculations and assumptions are based on the information provided in the problem statement. If there are any additional details or constraints, please let me know so that I can provide a more accurate answer.
