Finding Areas in Floor Plans

In this lesson, students learn to apply their knowledge of area to determine the areas of rooms in a floor plan. The video covers strategies such as multiplying side lengths, decomposing and adding, and subtracting smaller rectangles. Examples include calculating the area of a living room, bathroom, bedroom, hallway, and kitchen. The lesson concludes with a practice question for students to apply what they've learned.
