Question

Длина прямоугольного садового участка 30 м, а ширина в 3 раза меньше. Сколько потребуется щитов, длиной по 2 м, чтобы оградить весь участок?

Answer 1

30:3=10(м)-ширина.
( 30+10)*2=80(м)-периметр
80:2=40 (щитов)-понадобится.
Ответ: 40 [/tex]щитов.

Answer 2

Calculating the Number of Fence Panels Needed

To calculate the number of fence panels needed to enclose the entire rectangular garden plot, we can use the given dimensions of the plot and the length of the fence panels.

Given: - Length of the garden plot = 30 m - Width of the garden plot = 3 times less than the length (i.e., 30 m / 3 = 10 m) - Length of each fence panel = 2 m

Calculation:

1. Calculate the perimeter of the garden plot: - Perimeter = 2 * (length + width) - Perimeter = 2 * (30 m + 10 m) - Perimeter = 2 * 40 m - Perimeter = 80 m

2. Calculate the number of fence panels needed: - Number of fence panels = Perimeter / length of each panel - Number of fence panels = 80 m / 2 m - Number of fence panels = 40 panels

So, to enclose the entire garden plot, 40 fence panels will be needed.
