I painted some trapezoidal roofs. If the top side is 5 centimeters (cm), the bottom side is 9 centimeters (cm), and the area is 56 square cm (cm 2), what is the height in centimeters (cm) of this roof?
56 2 [OP_MUL] 5 9 [OP_ADD] [OP_DIV]
var_a = 56
var_b = 2
var_c = var_a * var_b
var_d = 5
var_e = 9
var_f = var_d + var_e
var_g = var_c / var_f
print(int(var_g))
