Answer: 
Step-by-step explanation:
We know that the area of the living room can be calculated with the formula for find the area of a rectangle. This formula is:

Where:
is the lenght of the original living room, and
is the width of the original living room.
If he creates the addition that causes the dimensions to triple, then the new area of Garrett’s living room is:

We know that :
Ф Product of the slopes of two lines perpendicular to each other should be equal to -1
Let the slope of the line perpendicular to given line be : M
Given equation of the line : y = -1/2x + 4
This line is in the form : y = mx + c, where m is the slope and c is the y intercept
Comparing with y = mx + c :
we can notice that slope of the given line is -1/2
⇒ M × -1/2 = -1
⇒ M × 1/2 = 1
⇒ M = 2
<u>Answer</u> : Slope of the line perpendicular to given line is 2
