What is the cost of leveling the field in the form of parallelogram at the rate of Rs.50/10 sq.metre, whose base & perpendicular distance from the other side being 54m & 24m respectively? Choose the correct choice from the following:
A) rs . 5280  B) rs . 5500  C) rs . 6000  D) rs . 6480  E) rs . 7680

Rationale: area of the parallelogram = length of the base * perpendicular height = 54 * 24 = 1296 m . total cost of levelling = rs . 6480 d
Answer: D
