20. 3/6 points | Previous Answers SCalcET8 4.7.037 My Not A piece of wire 15 m long is cut into two pieces. One piece is bent into a square and the other is bent into an equilateral triangle. (a) How much wire should be used for the square in order to maximize the total area? 15 (b) How much wire should be used for the square in order to minimize the total area? 13.10 Enhanced Feedback Please try again and draw a diagram. Keep in mind that the area of a square with edge a is As = a2 and the area of an equilateral triangle with edge b is At square, which means x = 4a, and y be the perimeter of the triangle, which means y = 3b. Find a relationship between x and y, considering that the wire's length , is a constant and-x + y. Rewrite the total area A = As + At as a function of one variable. Use calculus to find the edges of the square and the triangle that maximize the area; then find the edges that minimize the area Need Help? =--.
