Answer:
#include <iostream>
using namespace std;
int main()
{
int length = 8;
int width = 8;
int perimeter = 2*(length + width);
int area = length * width;
cout<<"The perimeter is "<<perimeter<<endl;
cout<<"The area is "<<area<<endl;
return 0;
}
Explanation:
include the library iostream for using the input/output instructions in the c++ programming.
Create the main function and define the variable length and width with values.
Then, use the formula for calculating the perimeter and area of rectangle.


and store in the variables and finally print the output.
Answer:
Option C is correct.
Explanation:
When the supply of system engineers rises while demand for such workers falls at the similar period, Wages will drop while competition for employment rises.
According to the law of demand, when the supply of one commodity is increased then the demand for other commodity falls. So, the following option C is correct according to the following scenario.
Other options are incorrect because they are not relevant according to the following scenario.

These companies develop their own software that enables them to build and maintain searchable databases of web pages (the engine), and to organise those pages into the most valuable and pertinent way to the user.</span>
Answer:
Explanation:
The following class is written in Java. I created the entire Circle class with each of the methods and constructor as requested. I also created a tester class to create a circle object and call some of the methods. The output can be seen in the attached picture below for the tester class.
class Circle {
double radius;
public Circle(double radius) {
this.radius = radius;
}
public double getRadius() {
return radius;
}
public void resetRadius() {
radius = 0;
}
public double calculateArea() {
double square = Math.pow((Math.PI * radius), 2);
return square;
}
}
