This time rectangle R has varying length l and width w but with a constant area of 4 square feet.

a) Express the perimeter P as a function of length l. What type of function is P? What is the domain of P?

b) Describe the asymptotic behavior of P. What can you say about rectangle Rbecause of this behavior? Could you have made a similar statement about Rback in Task 1?

c) For what values of land w will the perimeter of R be the least? Give a geometric explanation. Be sure to include a graph with relevant p

I need help fast please anyone!!!
I'm not good at math at all!!
