a recatngular hall 12 metres long,10 metres broad is surrounded by a varandah 2 metres wide.find the area of the veranda?

• 104 sq.m
  
  Area of verandah = area of (rectangle + verandah) - area of rectangle
  
  Area of (rectangle + verandah) = (12 + 4)(10 + 4) = 16*14 = 224 sq.m
  Area of inner rectangle = 10*12 = 120 sq.m
  
  => Area of verandah = 224 - 120 = 104 sq.m

• Area of the veranda=2(width of the veranda)*[length+breadth of the room + 2*(width of veranda)]
  hence, area of veranda=2*2*[12+10+(2*2)]=4*26=104 m^2 ans.

• ANS : 104 sq.m
  Area of verandah = area of (hall + verandah) - area of hall
  => (12+4)(10+4) - 10*12 = 104 sq.m
  [4 is added because hall is surrounded by a varandah 2 metres wide from all side so 2+2 ]

• ans=104 sq.m
  area of veranda = (12*2)*2 + (10*2)*2 + (2*2)*4= 48+40+16 =104 sq.m
  OR
  area of veranda= outer are - inner area
  =(12+4)*(10+4)-12*10
  =16*14 - 120
  =224-120 = 104 sq.m
