Hello :
<span>a single expression is : A = xy +zk
x : </span> width1 y : <span>length1
z : </span>width2 k : <span>length2
A : </span><span>the total area of the two rooms
note :
A1 = xy ........</span>area of the room 1<span>
A2 = zk </span>.......area of the room 2
Find the slope of the line passing throught the points (2, 2) and (4, 3).
The formula of a slope:

Substitute:

If the point (x, -1) lie on the same line, then the slope of line passing through the points (2, 2) and (x, -1) the same:
Substitute:

We have the equation:
<em>cross multiply</em>

<em>add 2 to both sides</em>

<h3>Answer: x = -4.</h3>
