Answer: 
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
- By definition, the perimeter of the figure is the sum of the lenght of each side. Then, you must make the addition as following:

Where
is the perimeter of the figure.
- Add the like terms, then, you obtain the following expression in simplest form:

4( 40 - 30)
subtract 30 from 40 is expressed as 40 - 30
then multiply by 4 is expressed as 4 × (40 - 30) or 4(40 - 30) = 40
20 because if you think about it 2/3 is equal to 20/30.

Here we have a line given by the equation:

This line is given in Slope-intercept form, recall that this form is as follows:

So in this case:

So a point that lies on the line is:

Another point would be:

So the line must pass through these two points. By using graphing tool we get the line shown below.
