2-19.

The diagram below is the floor plan of Randy's apartment. All measurements are in feet. Use the diagram to answer the following questions.

1. What are the dimensions (length and width) of Randy's living room?

Label the rest of the sides of the rectangles with the lengths directly across from them.

Don't forget about your units!

2. Randy's friends are coming to visit him soon. He plans to keep them out of his bedroom. Find the area of each of the other three rooms he will have to clean.

Area is the total square units of a shape. In this case, the length multiplied by the width.

The area of the bathroom is $63\ \text{feet}^2$, since $(7)(9)=63$. What are the areas of the kitchen and the living room?

3. What is the total area of the rooms he will have to clean?

Sum the answers in part (b).

$318$ square feet
