Kindly answer the question in python coding and functions format

Create a nested function as per the instructions given below: The outer function has to calculate the perimeter of a rectangle which is given by 2( length+breadth). The inner function should calculate the sum (length+breadth) and return it to the outer function to complete the calculation. Using the function above, calculate the perimeter of the two rectangles below: i) length =100m, breadth =300m ii) length =250m, breadth =500m
