A triangle is said to be an 'Equable Triangle', if the area of the triangle is equal to its perimeter. Write a program to enter three sides of a triangle. Check and print whether the triangle is equable or not.
For example, a right angled triangle with sides 5, 12 and 13 has its area and perimeter both equal to 30.

Rewrite the following code using single if else statement:

if (brd.equals("ICSE")) {
    if (code == 86) {
        System.out.println("ICSE Computer Applications");
    }
    else {
        System.out.println("Unknown subject");
    }
}
else {
    System.out.println("Unknown subject");
}
