A verandah of width 2.25 m is constructed all along he outside a room which is 5.5 m long and 4 m wide.
Find:
(i) The area of the verandah
(ii) The cost of cementing the floor of the verandah at the rate of Rs. 200 per m2.
(i) It is given in the question that,
Length of room = 5.5 m
Breadth of room = 4 m
We know that,
Area of rectangle = Length × Breadth
∴ Area of room = 5.5 × 4
= 22 m2
From the figure it can be observed that the new length and breadth of the given room (When verandah is included) is 10 m and 8.5 m respectively
∴ Area of room including verandah = 10 × 8.5
= 85 m2
Area of verandah = Area of the room including verandah – Area of room
= 85 – 22
= 63 m2
(ii) It is also given in the question that,
Cost of cementing 1 m2 area of the floor of the verandah = Rs 200
∴ Cost of cementing 63 m2 area of the floor of the verandah = 200 × 63
= Rs 12600
