Final answer:
To develop a Visual Basic app to calculate the area of a rectangle, you would design a user interface, apply area calculation logic, and compare areas using proportions.
Step-by-step explanation:
Developing a Visual Basic Application to Calculate Rectangle Area
To develop a Visual Basic application for calculating the area of a rectangle, start by creating a user interface with two text boxes for the length and width input. Then, add a button a user can click to execute the area calculation. In the button click event handler, write code to retrieve input values, calculate the area by multiplying length times width, and finally, display the result in a label or text box. Ensure to handle possible input errors, such as non-numeric values, by using exception handling or input validation techniques.
Comparing Rectangle Areas
When comparing the area of two rectangles, calculate each area separately and use a proportion or ratio to express how one area relates to the other. To do this, divide the area of the larger rectangle by the area of the smaller rectangle, which gives you the factor by which the larger rectangle's area is bigger than the smaller one.
