Challenge: Consoling Meaningful Output

In earlier tasks, we worked with raw numbers, but didn't provide any explanation or context for those numbers. It's essential to accompany the numbers with meaningful text so that the user understands what they represent. In this task, you will extend the previous task by adding text to your output.

Write a console.log statement to display following output:

The area of a trapezium is equal to 170 units.

Note

Do not hardcode the value 170 into the output, rather write the arithmetic expression for it based on the given numbers, 13, 21 and 10, so that it's calculated first - the same as how it was done in the previous task. The formula is given below for reference.
