The areas of the following figures are computed as follows: 1. trapezoid: (h/2) (b1+b2) 2. ellipse: T (r1+r2) 3. equilateral triangle: V3(a*) 4 Using switch for the choices, write a Java program that will display a menu and the user can choose which figure to compute. When the user decides whether 1. Trapezoid, 2. Ellipse, or 3. Equilateral Triangle, compute the area of the figure chosen and output the results. Depicted below are sample outputs when the program is executed (the items in bold characters are inputted by the user, while the items in bold italic characters are calculated and outputted by the program): Menu: Compute Area of 1.

Instruction:
The areas of the following figures are computed as follows:
1. trapezoid: (h/2) (b1+b2)
2. ellipse: T (r1+r2)
3. equilateral triangle:
3(a*)
4
Using switch for the choices, write a Java program that will display a menu and the user
can choose which figure to compute. When the user decides whether 1. Trapezoid, 2.
Ellipse, or 3. Equilateral Triangle, compute the area of the figure chosen and output the
results.
Depicted below are sample outputs when the program is executed (the items in bold
characters are inputted by the user, while the items in bold italic characters are
calculated and outputted by the program):
Menu: Compute Area of
1. Trapezoid
2. Ellipse
3. Equilateral Triangle
Choice: 1
Menu: Compute Area of
1. Trapezoid
2. Ellipse

Choice: 3
Trapezoid
Enter h: 3
Ellipse
Enter rl: 2
Equilateral Triangle
Enter a: 3
Area of Equilateral
Triangle is 3.9
Enter bl: 2
Enter r2: 3
Enter b2: 2
Area of Ellipse is 18.85
