Since your balcony is 2m wide, length of the balcony would be
8.5m+2m+2m = 12.5m
similarly you can calculate the other dimension
4.5m+2m+2m = 8.5m
now,
area_of_balcony_and_room = area_of_balcony + area_of_room
or,
area_of_balcony = area_of_balcony_and_room - area_of_room
therefore,
area_of_balcony = 12.5*8.5 - 8.5*4.5 = 68sqm
