This math topic focuses on the application of Cartesian grid geometry alongside perimeter calculation for rectangles. It involves problems where students are required to find a missing y-coordinate of a vertex of a rectangle given its perimeter, including scenarios where the coordinates may be negative. The problems are designed to assess the student's ability to combine knowledge of the Cartesian grid system and the formula for the perimeter of rectangles in a logical manner. There are multiple choice answers available for each question, testing the student’s ability to apply these concepts correctly.
