One farm has a rectangular fence. This fence is 30 meters (m) in circumference, and its width is twice as long as its length. Find the width of the fence in meters (m).
30 2 [OP_DIV] 1 2 [OP_ADD] [OP_DIV] 2 [OP_MUL]
var_a = 30
var_b = 2
var_c = var_a / var_b
var_d = 1
var_e = 2
var_f = var_d + var_e
var_g = var_c / var_f
var_h = 2
var_i = var_g * var_h
print(int(var_i))
