length of varandah including room = 10+ 2+2 = 14 m
breadth of varandah including room = 8+2+2 =12 m
area of verandah including room = 14 × 12 = 168 m^2
area of rectangular room = 10 × 8 = 80 m^2
area of verandah = area of verandah including room - area of rectangular room
area of verandah = 168 - 80 = 88 m^2
breadth of varandah including room = 8+2+2 =12 m
area of verandah including room = 14 × 12 = 168 m^2
area of rectangular room = 10 × 8 = 80 m^2
area of verandah = area of verandah including room - area of rectangular room
area of verandah = 168 - 80 = 88 m^2
