Perimeter of a Rectangle - Missing Square Corner

This math topic centers around calculating the perimeter of rectangles with a missing square corner. The problems involve adjusting standard perimeter calculations to account for this missing section. Each question is presented with a rectangle image showing the altered shape, and students must select the correct perimeter from multiple choices. This focus sharpens skills in spatial visualization and applying perimeter formulas to unconventional polygon shapes, and is part of a larger unit on the area and perimeter of basic shapes.
