Task 2 Rectangle R has varying length ℓ and width w but a constant area of 4ft2. 4 ft 2 . 4 , ft squared , . Express the perimeter P as a function of ℓ. What kind of function is P? What is its domain? Describe the asymptotic behavior of P. What can you say about R because of this behavior? Could you have made a similar statement about R in Task 1? For what values of ℓ and w will the perimeter of R be least? Give a calculator-based argument. Give a geometric argument. BIG idea Function
