1-6.

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

1. Find the area of her living room.

Area is the total square units inside a shape.

Area of a rectangle is base multiplied by height.

Base $=15$; Height $=18$

$15(18)=270$

Reminder! Don't forget your units. ft ( ft ) = ft2

$270$ ft2

1. Find the area of her entire apartment.

The base of the rectangle you are trying to find the area of is $15+8$.

$644$ ft2

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

Find the area of both rooms and subtract the area of the bedroom from the area of the living room.

The base of the rectangle you are trying to find the perimeter of is $8$.

$52$ feet
