This math topic focuses on calculating the perimeter of a rectangle when one of the corners is missing, forming a new shape. It involves understanding and applying the basic principles of perimeter in the context of modified rectangles, reinforcing skills in both perimeter calculation and problem-solving related to geometric shape alterations. Each problem requires identifying the composite lengths of the sides affected by the missing square corner to find the total perimeter. This topic is a specialized subset of learning about area and perimeter of basic shapes.
