Lesson objective: Apply area and perimeter formulas to real-world problems.

This lesson helps to build procedural skill of finding the area and perimeter. The four operations are used throughout the lesson, as students are asked to select a strategy based on the context of word problems. This work develops students' understanding that the relationship between operations can help solve real-world problems.

Students engage in Mathematical Practice 1 (Make sense of problems and persevere in solving them) as they self-select strategies by determining what information is given in a problem and what they are solving for.

**Key vocabulary:**

- area
- inverse
- perimeter
