Final answer:
The equation that reveals the dimensions that will create the maximum area of the prop section is A = -(x - 20)(40 - x). The dimensions that will create the maximum area are a width of 20 feet and a length of 20 feet.
Step-by-step explanation:
The equation that reveals the dimensions that will create the maximum area of the prop section is A = -(x - 20)(40 - x).
To find the dimensions that will create the maximum area, we need to maximize the equation A = -(x - 20)(40 - x).
We can do this by finding the x-value that corresponds to the maximum point on the graph of this equation. We can use a graphing calculator or algebraic methods such as completing the square or finding the vertex of a quadratic equation to find that the maximum area occurs when x = 20. Therefore, the dimensions that will create the maximum area of the prop section are a width of 20 feet and a length of (40 - 20) = 20 feet.
