Answer:

Rs 14,244

Step-by-step explanation:

Given that length of a rectangular field = 80 m

Breadth of a rectangular field = 60 m

Area of a rectangular field = length × breadth

= (80 × 60) m

Again, Area of the garden = 10 m × 40 m =

Area of 1 flower bed = 4 m × 1.5 m =

Thus, Area of two flower beds = × =

Remaining area of the field for applying manure = Area of the rectangular field - ( Area of the garden + Area of the two flower beds )

Remaining area of the field for applying manure =

Since = 1 acre

Therefore by using the above

= acres

So cost of applying manure at the rate of of Rs. 300 per acre will be = Rs. (300 × 47.48)

= Rs. 14,244
