Answer:

Step-by-step explanation:
We want to find the inverse of the function:

To find the inverse of a function, we will flip the variables and solve for <em>y</em>. So:

Solve for <em>y</em>. Subtract two from both sides:

Divide both sides by two:

And take the principal square root of both sides. Therefore:

Step-by-step explanation:
You can first multiply the width by two. Then you subtract that from you perimeter to figure out your length. Whatever number you get divide it by two and there's your length.
Example:
Perimeter =30 Width=5
5 times 2= 10
30-10=20
20/2=10
So your length equals 10.
