Create a function named area() that takes a single argument which will be a two-member tuple. area() should return the result of multiplying the first item in the tuple by the second item in the tuple.
i dont understand the task at all
dimensions = [ (5, 5), (10, 10), (2.2, 2.3), (100, 100), (8, 70), ]

A tuple is a data type that is similar to a list that contains multiple data items. A tuple differs from a list because it is immutable, that is, once defined it cannot change or be added to.
What the challenge is asking-- create a function "area()" that multiplies the first two items in a tuple and returns the value.
Here is an example that was done with an interactive Python REPL-- The ">>>" indicates where I typed something in to the interactive shell.
Python 3.7.4 (tags/v3.7.4:e09359112e, Jul 8 2019, 20:34:20) [MSC v.1916 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license()" for more information. >>> # let's name a tuple 'y' and put in three city names >>> y = ("Chicago", "Denver", "Portland") >>> # let's access the first or  item. >>> y 'Chicago' >>> y 'Denver' >>> # show that we can assign a new variable 'cities' to the value of 'y' >>> cities = y >>> cities 'Chicago' >>> cities 'Denver' >>> cities 'Portland' >>> # show that if we try to access an item that is not in the list, we get an error >>> cities Traceback (most recent call last): File "<pyshell#7>", line 1, in <module> cities IndexError: tuple index out of range >>> # suppose we have a simple dimension tuple variable named "x" >>> # note, a tuple is typically defined using parenthesis. >>> x = (5,5) >>> # we can easily create a function that can multiply the first and second items of the dimension >>> def area(dim): return dim * dim >>> # now, let's calculate an "area" of the dim variable >>> area(x) 25 >>>
I hope this helps your understanding! Good luck with your Python journey!
a tuple in python is a collection of data, for example:
("apple", "banana", "cherry") is a tuple with 3 items.
You are asked to make a function that takes a tuple (with two values as input) and will give the result of multiplying the two values in that tuple as a result.
That function should be named
