The width of the rectangular area is 125 m and the area is 105,000 m2. Find the perimeter of this area.

Formula for the area of a rectangle:

S = a * b, where a and b are the length and width of the rectangle.

Let us express the length of the rectangle in terms of the area formula:

a = S: b;

a = 105000: 125 = 840 m – the length of the rectangular section.

Formula for the perimeter of a rectangle:

Р = (a + b) * 2, where a and b are the length and width of the rectangle.

P = (840 + 125) * 2 = 965 * 2 = 1930 m – the perimeter of the rectangular section.

Answer: the perimeter of the rectangular section is P = 1930 meters.
