First, let's define our variables.


Let's call our width X(given)

and our length, since it's 10 shorter than 3 times the width, we can call our length:

3x-10

So, the perimeter of a rectange is equal to 2 times the length + 2 times the width.


So, when we plug our values in, we get

[tex]2(3x-10)+2x\\6x-20+2x\\8x-20[/tex]

The perimeter is 8x-20
