Hyejin tries to connect six pieces of paper in the shape of a square with a side length of 30 centimeters (cm) by gluing them together. When gluing was done, they overlapped each other by 7 centimeters (cm). How many square centimeters (cm²) is the area of the connected papers?
30 6 [OP_MUL] 7 6 1 [OP_SUB] [OP_MUL] [OP_SUB] 30 [OP_MUL]
var_a = 30
var_b = 6
var_c = var_a * var_b
var_d = 7
var_e = 6
var_f = 1
var_g = var_e - var_f
var_h = var_d * var_g
var_i = var_c - var_h
var_j = 30
var_k = var_i * var_j
print(int(var_k))
