Suppose you want to fence in an area and divide it into two adjacent, congruent regions by placing a barrier in the middle, parallel to the two shorter sides. You have 600 meters of fencing to use. Write a function that represents this situation, letting x = the width of the area. A. 2 600 3 A x x =-B. 2 3 300 2 A x x =-C. 2 3 600 2 A x x =-D. 2 300 3 A x x =-E. None of the above 5. Suppose you want to maximize the area of a region, and the function you write is ( ) (40 8 ) A x x x =-with domain [ ] 0,5 . Find the dimensions that will give the maximum area.
