Complete the following code by adding: (1)a function called areabox that takes two arguments, the length and width of the rectangle and returns the area of a rectangle. (2)a function called perimeterbox that takes two arguments, the length and width of the rectangle and returns the perimeter of a rectangle. (3)a function called rectangle that gets the length and the width of the rectangle from the user and displays the area and the perimeter of the corresponding rectangle.

The volume v and paper surface area a of a conical paper cup are given by where r is the radius of the base of the cone and h is the height of the cone. a. by eliminating h, obtain the expression for a as a function of r and v. b. create a user-de ned function that accepts r as the only argument and computes a for a given value of v. declare v to be global within the function. c. for v ! 10 in.3 , use the function with the fminbnd function to compute the value of r that minimizes the area a. what is the corresponding value of the height h? investigate the sensitivity of the solution by plotting v versus r. how much can r vary about its optimal value before the area increases 10 percent above its minimum value?
