The length of the rectangular section is 30 m and the width is 20 m. What is the length of the fence that encloses this section.
The rectangular section has the shape of a rectangle, and the length of the fence is its perimeter. We can find the perimeter in several ways. Let’s summarize all sides of the site:
30 + 20 + 30 + 20 = 50 + 50 = 100 m.
Since the opposite sides of the rectangle are equal, we can add the length and width and multiply by two:
2 (30 + 20) = 2 * 50 = 100 m.
Answer: the length of the fence is 100 m.
