This math topic focuses on calculating the missing side lengths of rectangles given the perimeter and the ratio of the sides. It forms part of a broader unit on the introduction to logic related to area and perimeter. Each question presents a different scenario to find a side length, aiming to strengthen understanding of how side ratios and perimeter relate in determining dimensions of rectangles.
