Have no idea how to do this

I think you use the for loop like how Kenneth did in the video and the attrgetter method but I don't know how to get [0] and [1] pair in the dimensions list to multiply.

maps.py 
from operator import attrgetter
dimensions = [
    (5, 5),
    (10, 10),
    (2.2, 2.3),
    (100, 100),
    (8, 70),
]

def area(argument):
    dimensions_result = (dimensions, key_attrgetter([0]*[1]))
    return dimensions_list

There are two parts to this challenge. The first part does not involve the dimensions list.

Just a simple function:

def area(arg):
    return arg[0] * arg[1]
