In the previous problem, we learned about rectangles with a fixed perimeter and how to find the width when given the length and area. This graph shows the length and area data for rectangles with a fixed perimeter of 40 meters. Use the graph below to solve the following problems. 180 160 140 120 Area 100 (m) 80 60 40 20 5 10 15 20 Length of a Side (m) The vertex of a function is the maximum or minimum point of the graph. What is the coordinate for the vertex of this graph? ( What is the largest area for this function? m What is the length for this area? m Pay attention to how these values relate to the vertex for this graph.
