Literary notes about Perimeter (AI summary)
Writers employ the term “perimeter” to evoke both concrete boundaries and abstract limits in their work. In military narratives, it delineates the tangible edges of a defended space—illustrated when sentries are stationed at the outer boundary of a fortification [1] or when troops set up a night perimeter [2] to protect their position. Meanwhile, in mathematical and scientific contexts, “perimeter” signifies the measured line around a figure, as in defining the circular boundary that encloses the maximum possible space [3, 4] or calculating the lateral area of a pyramid by multiplying its base’s perimeter by the slant height [5]. Through these diverse applications, the word enriches descriptions by blending physical borders with technical precision.
