A room 9.5 m long and 6 m wide is surrounded by a 1.25 m wide verandah. Calculate the cost of cementing the floor of this verandah at Rs.80 per $m^{2}$

Open in App

Solution

Area of room = $6 \times 9.5 = 57 m^{2}$
Area of room including verandah = $12 \times 8.5 = 102 m^{2}$
So area of verandah = $102 - 57 = 45 m^{2}$
So cost of cementing the floor of this verandah = $45 \times 80 = 3600 r u p e e s$
