Answer» EXPLAINED :length = 175m breath =96 area of the RECTANGLE = l×b = 175×96 = 16800 if the COST of fencing in 1m = 17 then the cost of fencing in 16800m = 17×16800 = 285600 and the cost of ploughing in 1m = 4.50 the cost of ploughing in 16800m = 450/100 ×16800 = 175600 area of TILES =s×s = 20×20 = 400 according to the room length the area of tiles =400×10 = 4000 by ADDING in 4.5m = 4000×4.5 = 18000 the tiles will be adding = 18000-4000 = 14000 if the cost of putting the tiles in 1m= 131.40 then the cost of putting the tiles in 14000m = 14000×131.40 = 1839600 |
