The area of the plot is rectangular 84 m2. The length of the section is 14 m.

The area of the plot is rectangular 84 m2. The length of the section is 14 m. How many meters of wire is required to fence the section around the perimeter.

As you know, the perimeter of a rectangle is:

P = 2 * (a + b), where a is the length of the rectangle, b is its width.

We know the length of the section, so we need to find its width.

According to the condition of the problem, the area of this site is 84 m (sq.).

Since the area of the rectangle is S = a * b, then

b = 84: 14 = 6 (m).

Knowing the length and width of the site, we can easily calculate its perimeter:

P = 2 * (14 + 6) = 2 * 20 = 40 (m).

Answer: 40 m.
