A trapezoid with a base of 25 centimeters (cm) and a height of 13 centimeters (cm) has an area of 286 square centimeters (cm2). How many centimeters (cm) is the length of the upper side of this trapezoid?
286 13 [OP_DIV] 2 [OP_MUL] 25 [OP_SUB]
var_a = 286
var_b = 13
var_c = var_a / var_b
var_d = 2
var_e = var_c * var_d
var_f = 25
var_g = var_e - var_f
print(int(var_g))
