Summarize this article in one sentence.
For a square of side length S, the perimeter is simply four times the side length: P=4s. Depending on the assignment, you may need to measure the side with a ruler, or look at other information on the page to determine the side length. Here are some examples of perimeter calculations: If your square has a side length of 4, then P = 4 * 4, or 16. If your square has a side length of 6, its P = 4 * 6, or 24.
Recall the formula for the perimeter of a square. Determine the length of one side, and multiply it by 4 to find the perimeter.
