A verandah 1.25m wide is constructed all along the outside of a room 5.5cm long and 4m wide.Find the cost of cementing the floor of this verandah at rate of rupees 15per sq.m

Answer 1

Given that the verandah is constructed along the side of room 5.5 m therefore verandah length will be 5.5 M long according to question area of under is equals to length into breadth therefore5.5m *1.25m that is equals to 6.875 and cost of cementing floor of veranda equals to 6.875 into 25 that is equals to 171.875

Answer 2

Area of the room is given by 4 * 5.5 = 22m2

Area of the verandah with room is (5.5 + 1.25 + 1.25) * (4 + 1.25 + 1.25) = 8 * 6.5 = 52

Area of only verandah = 52 - 22 = 30m2

Cost of cementing the floor of the verandah = 15 Rs/m2

Total cost of cementing 30m2 verandah = 30 * 15 = 450 Rs
