Sure, here is a simple Python program that calculates the value of s using the formula s=(a+5)*b:

a = float(input("Enter the value of a: "))
b = float(input("Enter the value of b: "))
s = (a + 5) * b
print(f"The value of s is: {s}")

You can run this program in any Python compiler or interpreter by providing the values of a and b when prompted. The program will then calculate and display the value of s using the formula (a+5)*b.
