Two identical rectangular-shaped postcards were attached horizontally so that they did not overlap. If the entire perimeter of the stitched postcard is 70 centimeters (cm) and the vertical length is 15 centimeters (cm), how many square centimeters (cm2) is the area of one postcard?
70 2 [OP_DIV] 15 [OP_SUB] 15 [OP_MUL] 2 [OP_DIV]
var_a = 70
var_b = 2
var_c = var_a / var_b
var_d = 15
var_e = var_c - var_d
var_f = 15
var_g = var_e * var_f
var_h = 2
var_i = var_g / var_h
print(int(var_i))
