1. Area of Square
2. Area of Rectangle
3. Area of Triangle
Structure of the Problem Requirements
In this Problem we Calculate the Area of Different Geometric term like Square, Rectangle and Triangle. This Problem is Solved in Netbeans IDE which is very Popular for making Desktop Application. After getting the Formulas of these Geometric term we used Card layout to Display the required result against the their name.
