Perimeter of a Rectangle - Side from Perimeter and Side

This math topic focuses on determining the missing side lengths of rectangles given their perimeters. It involves applying the formulas for the perimeter of a rectangle and understanding the relationship between side lengths. The topic forms an introductory part of a broader unit on area and perimeter logic, aimed at developing geometric problem-solving skills. Each question presents a rectangle with certain dimensions provided and requires the calculation of an unknown side length. The problems, designed for an introductory level, reinforce foundational geometric concepts and analytical thinking in a practical context.
