For example, lets say we select circle, we need only radius in order to calculate circle area. All of these parameters value insertion must be using combo box. The formula for all shapes are: (i) Acircle-TXTadius 2, (ii) Atriangle # 2xbasex height, (iii) Arect angle width length, (iv) Atrapezoid 2 calculate the area based on the inserted information. For this example, lets say the circle radius is 7, user should get *(7*7) = 153938040026 baseA+baseB height, when user press "Calculate Area" button, the system Basic Shape Area Calculation System Put example image in static text to show each items Please select your shape: Static text Radio button Your selection isCIRCLE Combo Box Circle radius: Calculate Area Button Edit text The circle area is
