There is a piece of colored paper in the shape of a square with a side length of 4 centimeters (cm). The four sides of this colored paper were cut into diamond shapes by connecting the two equally divided dots. Find the area of this rhombus.
4 4 [OP_MUL] 2 [OP_DIV]
var_a = 4
var_b = 4
var_c = var_a * var_b
var_d = 2
var_e = var_c / var_d
print(int(var_e))
