Rectangle with an area of 21 hectares. determine the perimeter if its width is 250 m.

Consider the condition of this problem. When solving, geometric formulas will be applied. Let’s find a solution to the task by actions with detailed explanations for each of them:
1. Let’s transform the values: in 1 hectare there are 10,000 square meters. Accordingly, 21 ha = 210,000 m².
2. Area of ​​the rectangle = width × length. Let us express the length: length = area ÷ width. Substitute numerical values ​​in the formula and calculate: length = 210,000 ÷ 250 = 840 m.
3. Perimeter of the rectangle = 2 × (width + length). Substitute the numerical values ​​into the formula and calculate what the perimeter is equal to: perimeter = 2 × (250 + 840) = 2180 m.
Answer: The perimeter of the rectangle is 2180 meters.
