If the area of a trapezoid with a base of 23 centimeters (cm) and a height of 12 centimeters (cm) is 222 square cm (cm2), what is the length of the upper side?
222 2 [OP_MUL] 12 [OP_DIV] 23 [OP_SUB]
var_a = 222
var_b = 2
var_c = var_a * var_b
var_d = 12
var_e = var_c / var_d
var_f = 23
var_g = var_e - var_f
print(int(var_g))
