This math topic focuses on calculating missing coordinates of a rectangle on a Cartesian grid by using given perimeters. Learners will apply their knowledge of Cartesian coordinates and geometry to determine missing x or y values that complete rectangles with specific perimeters. These problems involve only positive coordinate values and encourage the practice of perimeter calculations and logical thinking to solve for missing coordinates within the constraints of rectangular shapes.
