The area of an arbitrary triangle can be determined utilizing the formula:
Area = √s(s-a)(s-b)(s-c),
Where a, b and c signify the lengths of sides, and s is the semi-perimeter:
s = (a+b+c)/ 2
Write down a program in the visual basic which determines the area of a triangle. If three sides a, b and c entered do not make a triangle transmit the message out to the screen that the data entered was invalid. Use the textboxes, labels and the command buttons in order to implement the program.
