Perimeter of a Rectangle - Side from Perimeter and Side

Level 3

This math topic focuses on calculating the missing side of a rectangle given the perimeter and one side length. It's a part of a larger unit on introductory-level area and perimeter logic. The problems within the topic require students to apply the formula for the perimeter of a rectangle and basic algebra to solve for the unknown side. Each question presents a rectangle with one side length missing, and students are provided with a set of options to choose the correct length, testing their problem-solving and calculation skills in geometry.
