A trapezoidal canal with a side slope 2 ∶ 1 (horizontal : vertical) is to be formed in cutting for conveying water to a field. The dimensions of the canal are as follows: Bottom width of canal = 2 m; Depth of canal = 1 m. Work out the cost of lining the canal (in Rs.) using Geotextile material per km length. Assume the rate of lining canal with Geotextile material as Rs. 100 per Sq.m:
1
400000
2
200000 (1 + \(\sqrt{3}\))
3
250000
4
200000(1 + \(\sqrt{5}\))
