A square has been made by arranging several rectangular pieces of colored paper of the same size so that there are 8 pieces on each side. If you place more pieces around the perimeter of this square, how many more pieces will you need?
8 4 [OP_MUL] 4 [OP_ADD]
var_a = 8
var_b = 4
var_c = var_a * var_b
var_d = 4
var_e = var_c + var_d
print(int(var_e))
