Minjin made a square shape with one side length of 80 centimeters (cm) using wire. If you use the same length of wire to make a rectangular shape with a vertical length of 100 centimeters (cm), find the horizontal length of this rectangle.
80 4 [OP_MUL] 2 [OP_DIV] 100 [OP_SUB]
var_a = 80
var_b = 4
var_c = var_a * var_b
var_d = 2
var_e = var_c / var_d
var_f = 100
var_g = var_e - var_f
print(int(var_g))
