Answer 2

Program to Calculate the Area of a Square with Side A

To calculate the area of a square with side A, you can use the formula S = a * a = a^2. Here's a program to calculate the area of a square with side A in Python:

# Input the value of side A
a = float(input("Enter the length of the side A: "))

# Calculate the area
area = a * a

# Print the area
print("The area of the square is", area)

Explanation

The area of a square is calculated by multiplying the length of one side by itself. This can be represented by the formula S = a * a = a^2, where S is the area and a is the length of the side of the square.

When the value of side A is input, the program calculates the area by multiplying the value of side A by itself and then prints the result.

Example

For example, if the length of side A is 4 units, the area of the square would be: S = 4 * 4 = 16.

This means that the area of the square with a side length of 4 units is 16 square units.

Now you can use this program to calculate the area of a square with any given side length A.
