Question

Ramesh has a rectangular field of length 80 *60 it has a square garden of size 20 m and 5 circular flower beds each of radius 10m in the remaining part he wants to apply manures find the cost of applying manures at the rate of 30/- per m sq

Answer 1

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

$= 4800 m^{2}$

Again, Area of the garden = 10 m × 40 m = $40m^{2}$

Area of 1 flower bed = 4 m × 1.5 m = $6m^{2}$

Thus, Area of two flower beds = $2$ × $6$ $m^{2}$ = $12$

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 = $4800$ $m^{2}$ $- ( 40 + 12)$

$=(4800 - 52)m^{2}$

$=4748m^{2}$

Since $100$ $m^{2}$ = 1 acre

Therefore by using the above

$4748$ $m^{2}$ = $47.48$ acres

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

= Rs. 14,244
