Answer:
//Define class
public class Main {
//define main method
public static void main(String[] args)
{
//declare and initialize the double type variable to 128
double mexico = 128;
//declare and initialize the double type variable to 323
double us = 323;
//declare and initialize the integer type variable to 0
int yr = 0;
//set the while loop to check which is greater
while (mexico < us)
{
//increment in the variable by 1
yr++;
//initialize in the variables acc. to the percentage
mexico *= 1.0101;
us *= 0.9985;
}
//print the following results
System.out.println("Population of the Mexico will be exceed the population U.S. in " + yr + " years");
System.out.println("Population of the Mexico will be " + mexico + " million");
System.out.println("and population of the U.S. will be " + us + " million");
}
}
<u>Output</u>:
Population of the Mexico will be exceed the population U.S. in81 years
Population of the Mexico will be 288.88435953355025 million
and population of the U.S. will be 286.0198193927948 million
Explanation:
<u>Following are the description of the program</u>.
- Firstly, we define the class 'Main' and inside it, we define the main method.
- Then, declare two double data type variables which are 'mexico' and 'us' and initialize in it to 128 and 323.
- Declare integer data type variable 'yr' and initialize in it to 0.
- Set the while loop and pass the condition to check that the variable 'mexico' is less than the variable 'us' then, increment in the variable 'yr' by 1 and multiply the variables 'us' and 'mexico' by the following percentage.
- Finally, print the following results with the message.
<h2>Solution :</h2>
The given problem is solved in Python.
def ComputeSquare():
side = float(input('Enter the side of the square: '))
if side > 0:
perimeter = 4 * side
area = side * side
print('Perimeter of the square is:',
perimeter, 'unit.')
print('Area of the square is:', area, 'square unit.')
<h3> else:</h3>
print('Invalid input.')
ComputeSquare()
<h2>Explanation :-</h2>
- In this program, we create a function ComputeSquare() to calculate the perimeter and area of a square.
- The function asks the user to enter the side of the square. The side is then stored in a variable.
- Now, we check whether the side is greater than 0 or not using if-else statement.
- If the condition is true, the perimeter and area is calculated which is displayed using print() statement.
- If the condition is false, the else blocks executes printing the error message.

Answer:
48
Explanation:
The function returns length * width
In the function call, the values are legnth: 8 and width: 6 this means the function is returns 8 * 6 wich is 48.
