A-74.

The diagram at right is the floor plan of Randy’s apartment. The living room is $15$ feet long, and one of the walls of the bedroom is $10$ feet.

1. What are the dimensions of the bathroom?

The bathroom shares one wall with the kitchen and another wall with the bedroom.
Finding the lengths of these walls will help you find the dimensions of the bathroom.

$9 \text{ ft } \times 7 \text{ ft}$

2. Randy’s friends are coming to visit him soon. He will not need to clean his bedroom since he plans to keep his friends out of his bedroom. But he will have to clean the rest of the house. How much area will he have to clean?

Add the areas of each of the rooms together. Do not include the area of the bedroom.
