Question

11. A dance hall 11.8 m long and 4 m wide is surrounded by 0.75 m wide verandah all around. Calculate the cost
of cementing the floor of the verandah at 95 per m.
​

Answer 1

Answer:

Area of verandah = 2(11.8×.75)+2(4×.75)

= 17.7+6

= 23.7 m^2

cost of cementing the floor of the verandah = 23.7×95 = 2251.5 rupees ans.

Answer 2

Step-by-step explanation:

Length after including verandah=L+2×k=13.3m

Breadth after including verandah=B+2×k=5.5m

S

so, area including verandah=13.3×5.5=73.15 sq m

So, area of verandah=73.15-47.2=25.95sq m

Total cost=95×25.95=₹2465.25
