What is the cost of leveling the field in the form of parallelogram at the rate of Rs.40/10 sq.metre, whose base & perpendicular distance from the other side being 24m & 34m respectively?  Choose the correct choice from the following:
A) s. 600
B) s. 630
C) s. 640
D) s. 648
E) s. 816
Area of the parallelogram = Length of the base * Perpendicular height   = 24 * 34=
