How To Find The Area of a Parallelogram in Golang?

In this tutorial, we are going to see the Golang program to find the Area of a Parallelogram. The area is the total space covered by any closed figure.

Formula

Area of the Parallelogram - base * height
b - length of the base of a Parallelogram
h - length of the height of a Parallelogram

For example, the length of the base of a Parallelogram is 6 cm and the length of the height of the parallelogram is 4 cm so the Area of a Parallelogram is ?

b = 6 cm
h = 4 cm
Area = base * height
   = 6 * 4
   = 24 cm^2

Finding the Area of a Parallelogram within the function

Algorithm

Step 1 ? Declaring the variables for the length of the base, length of height, and the area of the float64 data type.

Step 2 ? Initialize the variable.

Step 3 ? Find the Area using the above formula within the function.

Step 4 ? Printing the result.

Time Complexity:
O(1)

Space Complexity:

Example 1

In this example, we are going to find the Area of a Parallelogram within the function.

Output

Program to find the Area of a Parallelogram.
The Area of a Parallelogram with base = 6 and height = 4 is 24 cm * cm.
(Finding the Area of a Parallelogram within the function)

Finding the Area of a Parallelogram in the separate function

Algorithm

Step 1 ? Declaring the variables for the length of the base, length of height, and the area of the float64 data type.

Step 2 ? Initialize the variable.

Step 3 ? Calling the function with the length of the base of the Parallelogram and the length of the height of the Parallelogram, and storing the Area the function is returning.

Step 4 ? Printing the result.

Example 2

In this example, we are going to find the Area of a Parallelogram by defining the separate function to find the Area.

Conclusion

These are the two ways to find the Area of a Parallelogram in Golang. The second way is much better in terms of modularity and code reusability as we can call that function anywhere in the project. To learn more about go you can explore these tutorials.
