Answer 1

import numpy as np


def GetPerimeter(I):
    Input = np.array(I)
    row, col = Input.shape
    P=0
    for r in range(0,row): P = P + Input[r][0]
    for c in range(1,col): P = P + Input[row-1][c]
    for c in range(1,col): P = P + Input[0][c]
    for r in range(1,row-1): P = P + Input[r][col-1]
    return(P)    


#Find perimeter of a matrix
Input = [
            [1,2,3],
            [4,5,6],
            [7,8,9]
        ]    
Perim = GetPerimeter(Input)
print("Input-1",Input)
print("Perimeter = ",Perim)


Input = [
            [1,2,3,4],
            [5,6,7,8],
            [9,10,11,12],
            [13,14,15,16]
        ]    
Perim = GetPerimeter(Input)
print("Input-1",Input)
print("Perimeter = ",Perim)
