Know how to calculate the perimeter of a square
Recently, hot topics and content across the entire network cover many fields such as technology, entertainment, and society. This article will combine these hot spots to answer a common mathematical problem: how to calculate the perimeter from the known area (square). At the same time, we will also present hot topics in the past 10 days in the form of structured data to help everyone better understand the current social dynamics.
1. How to calculate perimeter from area
In mathematics, area and perimeter are two different concepts. Area refers to the amount of space occupied by a flat figure, while perimeter refers to the total length of the figure's boundaries. For different shapes, the methods of calculating perimeter are also different. The following are calculation methods for several common graphics:
| graphics | area formula | Perimeter formula | How to calculate perimeter from area |
|---|---|---|---|
| square | Area = side length × side length | Perimeter = 4 × side length | Side length = √Area, Perimeter = 4 × √Area |
| round | Area = π × radius² | Perimeter = 2 × π × radius | Radius = √(area/π), perimeter = 2 × π × √(area/π) |
| Rectangle | Area = length × width | Perimeter = 2 × (length + width) | You need to know either the length or width to calculate the perimeter |
