This math topic focuses on identifying simple geometric shapes based on the formula used to calculate their perimeter. Specifically, it involves recognizing whether a description of a perimeter calculation corresponds to a triangle, square, or rectangle. It includes exercises where learners must match perimeter calculations like adding different sides or using multiples of a side length to the appropriate geometric shape, reinforcing their understanding of perimeter formulas for basic shapes in geometry.
