Following program shows you how to calculate trapezoid area.
This program gets trapezoid base and height from user and calculates area and prints it using following formula
Area = (base1 + base2) X height /2

import java.util.Scanner;

public class MathGeometry4 {

    public static void main(String[] args) {

        double trapezoidBase1;
        double trapezoidBase2;
        double trapezoidHeight;

        Scanner in = new Scanner(System.in);

        System.out.println("Please enter base1 of trapezoid:");
        trapezoidBase1 = in.nextInt();

        System.out.println("Please enter base2 of trapezoid:");
        trapezoidBase2 = in.nextInt();

        System.out.println("Please enter height of trapezoid:");
        trapezoidHeight = in.nextInt();

        double areaOfTrapezoid = (trapezoidBase1 + trapezoidBase2) * trapezoidHeight / 2;
        System.out.println("Area of trapezoid is: " + areaOfTrapezoid);

    }
}

Output:

Please enter base1 of trapezoid:
5
Please enter base2 of trapezoid:
8
Please enter height of trapezoid:
3
Area of trapezoid is: 19.5
