Hii buddy,

◆ Answer - Rs. 7800

◆ Explanation-
# Given-
l = 5 m
b = 1.5 m
h = 3 m
cost = 200 rs/sq.m

# Solution-
In septic tank we'll line only the sides (not top & bottom).

Therefore, total surface area to be lined -
A = 2 (lh + bh)
A = 2 (5×3 + 1.5×3)
A = 2 (15 + 4.5)
A = 2 × 19.5
A = 39 m^2

Total cost of lining -
Total cost = Area × cost
Total cost = 39 × 200
Total cost = 7800 Rs.

Thank you for asking...
