See below for a plot of the equation.
The y intercept is the y location where x=0 and can be found by solving 6y=180, which is y=30.
Likewise, the x intercept follows from y=0, so 4x=180 => x=45.
The interpretation of the intercepts is: what is the plan if you go for all small tables (ie., y=0) or all big tables (x=0). The answer is: you can rent either 30 small tables or 45 big ones.
All the other points on the line represent some mix of small and big tables (of course, x and y must be integer because you can't rent half tables).
Given:
Perimeter = 18 m
The formula for the perimeter of a rectangle is:
Where:
l = lenght
w = width
In this case, we have that:
l = 2w
Therefore, we substitute the values in the formula:
And solve for w:
For the length:
Answer:
The width is 3 m
The length is 6 m
