Question

Участок длиной 20 м и шириной на 5 м меньше длины обнесли забором, столбы которого находились на расстоянии 5 м друг от друга. Сколько потребовалось столбов для забора?

Answer 1

1) 20-5=15метров ширина

2) (20+15)х2= 70 метров 

3) 70:5=14 столбов

Answer 2

Calculation of Fence Posts for a 20m x 5m Plot

To calculate the number of fence posts required for a plot with dimensions 20m in length and 5m in width, we need to determine the spacing between the posts and then divide the total length of the fence by this spacing.

Given that the fence posts are placed 5m apart from each other, we can calculate the number of fence posts as follows:

1. Calculate the total length of the fence: - The length of the plot is 20m. - The width of the plot is 5m less than the length, which is 20m - 5m = 15m. - The total length of the fence is the sum of the lengths of the four sides of the plot: 20m + 20m + 15m + 15m = 70m.

2. Calculate the spacing between the fence posts: - The fence posts are placed 5m apart from each other.

3. Divide the total length of the fence by the spacing between the posts: - Number of fence posts = Total length of the fence / Spacing between the posts. - Number of fence posts = 70m / 5m = 14.

Therefore, 14 fence posts are required to enclose the plot.
