Question

Участок земли огородили забором из щитов, длина каждого из которых 3 М . сколько израсходовали таких щитов, если длина участка 100 М, а ширина в два раза меньше длины.

Answer 1

Calculation of the Number of Fence Panels Used

To calculate the number of fence panels used, we need to determine the perimeter of the garden.

Given: - Length of each fence panel: 3 meters - Length of the garden: 100 meters - Width of the garden: half the length of the garden

To find the perimeter of the garden, we can use the formula:

Perimeter = 2 * (Length + Width)

Substituting the given values:

Perimeter = 2 * (100 + (100/2))

Simplifying the equation:

Perimeter = 2 * (100 + 50) = 2 * 150 = 300 meters

Since each fence panel has a length of 3 meters, we can calculate the number of fence panels used by dividing the perimeter of the garden by the length of each panel:

Number of fence panels = Perimeter / Length of each panel

Substituting the values:

Number of fence panels = 300 / 3 = 100

Therefore, 100 fence panels were used to enclose the garden.
