a room 9.5 m long and 6m wide is surrounded by a 1.25 m wide verandah . calculate the cost of cementing the floor of this verandah at rs.80 per metre square

Answer 1

Area of room = 6×9.5 = 57 meter square . area of room including verandah = 12×8.5 = 102 meter square. so area of verandah = 102 - 57 = 45 meter square. so cost of cementing the floor of this verandah = 45 × 80= 3600 rupees
