1-39.

Susan's apartment is shown below. Assuming that all rooms are rectangular, find the quantities described below. All measurements are in feet.

 2 by 2 generic rectangle labeled as follows: Left edge top ↑ 10 ↓ interior top left Bedroom interior top right Bath Left edge bottom ↑ 18 ↓ interior bottom left Living Room interior bottom right Kitchen bottom edge left ←      15     → bottom edge right,  ←  8 →

1. Find the area of her living room.

Area is the total square units of a shape.

Area of a rectangle is base multiplied by height.

Base $=15$ Height $=18$

$15(18)=270$

Reminder! Don't forget your units. $\text{ft} \left(\text{ft} \right) = \text{ft}^2$

$270 \text{ ft}^2$

2. Find the area of her entire apartment.

Follow the steps in part (a).

$644 \text{ ft}^2$

3. How much larger than her bedroom is her living room?

Find both and subtract the smaller area from the larger area.
