width of varanda = 1.25
length of veranda = 5.5 because the room is connected with varanda so it's length will be same as room's length.
so, area of varanda = 5.5 * 1.25 = 6.875 m square
so, for cementing total cost will be = 6,875* 15
= 103.125

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
