Question

Длинна прямоугольного поля составляет 2м, а ширина 1м. Вбили 6 колышков на огорождение поля с интервалом между ними 20 см. Сколько еще колышков понадобится, чтобы огородить всю территорию?

Answer 1

Calculation of the Number of Additional Stakes Needed

To calculate the number of additional stakes needed to fence the entire area, we need to determine the number of intervals between the existing stakes and then add the number of stakes needed for those intervals.

Given: - Length of the rectangular field: 2 meters - Width of the rectangular field: 1 meter - Number of existing stakes: 6 - Interval between stakes: 20 cm

To find the number of intervals between the existing stakes, we can subtract 1 from the total number of stakes. In this case, the number of intervals is 6 - 1 = 5.

To find the total length of the intervals, we multiply the number of intervals by the interval length. In this case, the total length of the intervals is 5 * 20 cm = 100 cm.

To convert the total length of the intervals to meters, we divide it by 100. Therefore, the total length of the intervals is 100 cm / 100 = 1 meter.

To find the remaining length of the field that needs to be fenced, we subtract the total length of the intervals from the total length of the field. In this case, the remaining length is 2 meters - 1 meter = 1 meter.

Since the width of the field is 1 meter, we can conclude that the remaining length is also the remaining width.

To calculate the number of additional stakes needed, we divide the remaining length by the interval length. In this case, the number of additional stakes needed is 1 meter / 20 cm = 5 stakes.

Therefore, 5 additional stakes are needed to fence the entire territory.
