This math topic focuses on calculating the perimeter of triangles. Students solve a series of questions designed to enhance their understanding of triangular perimeter calculation. Each question involves a triangle for which students must determine the total length of the sides. Multiple choice answers are provided for each problem, challenging students to apply their knowledge and find the correct perimeter from the options given. This practice is part of a broader introduction to learning about perimeters.
