Perimeter of a Rectangle - Perimeter from Area and Side

Level 3

This math topic focuses on calculating the perimeter of a rectangle when given its area and one side length. It's part of an introductory unit on area and perimeter logic. The problems present the user with a rectangle, requiring them to deduce the second dimension from the area and known side length to compute the perimeter. Each question provides a rectangle's image with notations and multiple-choice answers. The goal is to apply understanding of both the perimeter formula and the relationship between the sides and area of rectangles.
