We are in the modern era and the information era
Hi, you haven't provided the programing language in which you need the code, I'll explain how to do it using Python, and you can follow the same logic to make a program in the programing language that you need.
Answer:
import math
def rectangle(perimeter, area):
l1_1 = (perimeter+math.sqrt((perimeter**2)-(16*area)))/4
l1_2 = (perimeter-math.sqrt((perimeter**2)-(16*area)))/4
l2_1 = area/l1_1
l2_2 = area/l1_2
print(l1_1,l2_1)
print(l1_2,l2_2)
if l1_1.is_integer() and l2_1.is_integer() and l1_1>0 and l2_1>0:
return(int(max(l1_1,l2_1)))
elif l1_2.is_integer() and l2_2.is_integer() and l1_2>0 and l2_2>0:
return(int(max(l1_2,l2_2)))
else:
return(None)
Explanation:
- We import math to make basic operations
- We define the rectangle function that receives perimeter and area
- We calculate one of the sides (l1_1) of the rectangle using the quadratic equation to solve 2h^2 - ph + 2a = 0
- We calculate the second root of the quadratic equation for the same side (l1_2)
- We calculate the second side of the rectangle using the first root on w = a/h
- We calculate the second side of the rectangle using the second root on w= a/h
- We verify that each component of the first result (l1_1, l2_1) is an integer (using the build-in method .is_integer) and greater than 0, if True we return the maximum value between them (using the max function) as w
- If the first pair of sides evaluate to False we check the second root of the equation and if they meet the specification we return the max value
- if all the if statements evaluate to false we return None to indicate that not positive or integer sides were found
Answer:
Statement to print phrase "Hello, world" and then start a new line in java.
System.out.println("Hello, world");
Explanation:
In java, we use "System.out.println();" statement to print any string/phrase and then start a new line.The above line will print phrase "Hello, world" and then start a new line.
Implementation in java:
// class definition
class Main
{
// main method of the class
public static void main (String[] args)
{
// statement to print phrase and start new line
System.out.println("Hello, world");
} }

Answer War Chalking
Explanation: War chalking is the technique for presenting the WiFi network publicly. This signifies about the WiFi is present but not describes the manner of it , that is whether it is open connection or closed connection.
It can be used by the people in general as well as hackers . Hackers usually tend to attack and hack its security that is present.Hackers then use the WiFi network is then used for their own work after being hacked.
