Program

import java.util.Scanner;
class AreaOfPentagon {
    public static void main(String args[]) {
        int apothem, side;
        float area, area_num;
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter the apothem:\t");
        apothem = sc.nextInt();
        System.out.println("Enter the length of side:\t");
        side = sc.nextInt();
        area_num = (5 * side * apothem);
        area = area_num / 2;
        System.out.println("Area of pentagon: " + area);
    }
}

Output

Enter the apothem:	
7
Enter the length of side:
