| It is known from the condition that the length of the section is 36.4 meters, and the width is 9.5 meters less. In order to find a fence of what length, you need to install on a given site.

Let’s first find the width of the lot.

36.4 – 9.5 = 26.9 meters width of the rectangle.

In order to find how long the fence needs to be installed on a given site, we need to find the perimeter of the site.

Let’s remember and apply the formula for finding the perimeter of a rectangle.

P = 2 (a + b);

Substitute and calculate:

P = 2 (36.4 + 26.9) = 2 * 63.3 = 126.6 meters fence length.
