Ruby program to calculate the area of Parallelogram

Last Updated : December 15, 2025

Problem Solution

In this program, we will read the base and altitude from the user. Then we will calculate the area of the Parallelogram and print the result.

Program/Source Code

The source code to calculate the area of the Parallelogram is given below. The given program is compiled and executed successfully.

# Ruby program to calculate the 
# area of Parallelogram

base=0.0;
altitude=0.0;
area=0.0;

print "Enter base: ";
base = gets.chomp.to_f;  

print "Enter altitude: ";
altitude = gets.chomp.to_f;  

area = base * altitude;

print "Area of Parallelogram is: ",area;

Output

Enter base: 3.13
Enter altitude: 4.6
Area of Parallelogram is: 14.397999999999998

Explanation

In the above program, we created three variables base, altitude, area, that are initialized with 0.0. Then we read base, altitude from the user and calculated the area of Parallelogram using the standard formula. After that, we printed the result.
