The perimeter of the rectangular ploy = 2(200 + 75.40) = 550. 8 m
Therefore 3 m opening is present so now the perimeter = 550.8 - 3 = 547.8
Therefore the cost = 5/m
Therefore the total cost = 547.8 * 5 = ₹2739

200m=200*100=20000cm
75m40cm=(75*100)+40=7540cm
3m=3*100=300cm
perimeter of a rectangular plot=2(l+b)
=2(7540+20000)
=2*27540=55080cm
cost of fencing=(55080-300)(cm)*5(m)
=547.8*5(m)
=₹2739
75m40cm=(75*100)+40=7540cm
3m=3*100=300cm
perimeter of a rectangular plot=2(l+b)
=2(7540+20000)
=2*27540=55080cm
