please help me with the questions below:

1a. 1b. A rectangular page is to contain 36 square inches of print. The margins at the top, bottom and on each side of the page are to be 1.5 inches. Find the dimensions of the page that will minimize the amount of paper used. Find the length and width of a rectangle that has a perimeter of 100 meters and a maximum area. 1c. The sum of the perimeters of an equilateral triangle and a square is 10. Find the dimensions 2a. 2b. of the triangle and the square the minimum total area. Find the production level that minimizes the average cost per unit for the cost function C = 400 + 0.05x + 0.0025162 , where C is the cost (in dollars) of producing x units of a product. What is the minimum average cost? A commodity has a demand function modeled by p = 80 0.2:: and atotal cost function modeled by C = 30x + 40, where x is the number of units. Find the production level that maximizes the prot. What price per unit yields the maximum prot. When the prot is maximized, what is the average cost per unit. 2c. The prot P (in dollars) made by a company from selling x tablet computers can be modeled x2 by P = 1.641: 15,000 prot. What is the maximum prot? 2500. Find the number of units sold that will yield a maximum
