The width of the plot is rectangular 1/5 and its length is 800 meters. Indicate the perimeter of this section.

The first step is to find the width of the rectangle. Let’s calculate the width, knowing that it is 1/5 of 800 meters.

800 * 1/5 = (800 * 1) / 5 = 800/5 = 160 meters.

To find a part of a number, you need to multiply this number by a part.

Let’s calculate the value of the perimeter, knowing that the length is 800 meters and the width is 160 meters.

P = 2 * (800 + 160) = 2 * 960 = 1 920 meters.

Answer: 1,920 meters.
