Apattern of rectangles is formed by decreasing the length and increasing the width, each by the same amount. the relationship between x, the amount of increase, and a, the area of the rectangle represented by the increase, is quadratic. which graph could represent the area of each rectangle in terms of the change in the length and width? mark this and return

Although the graph is not given in the option, so I would consider it from a different graph with the same question. The graph that represents the area of each rectangle in terms of the change in the length and width is the one with coordinate points located on the grid. The coordinate points on the form of (x,y) are represented as: 

1. (0,40)
2. (1,45)
3. (2,47) 
4. (8,25)

Hence,The graph with these coordinate points will be representing the situation.
