Length = 5.5-1.25×2=3m.
Breadth = 4-1.25×2=1.5m.
Aresa of verandah =l×b= 3×1.5=4.5m².
area of floor = l×b
5.5×4=22m² .
cost =22×25=€550m².answer.

Answer:
450 Rs
Step-by-step explanation:
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
