Answer:
Fencing is done at the perimeter so, perimeter of rectangular park=2(l+b)=2(350+250)
⇒2×600=1200m
Rate of fencing per meter=Rs. 18.50
∴ Rate of fencing 1200 m =Rs.8.50×1200
=Rs.22,200

Answer:
the area of rectangular park is 270 m²
it's length is 18 m
so it's breadth=
let the breadth be p
=length×breadth=270 m²
=18×p=270m²
p=270÷18=15 m
if the cost of fencing the park by wire is 25 per metres then total cost = in fencing we have to find perimeter
perimeter of retangular plot = 2×(l+b)
=2×(18+15)m
=2×33m
=66 m
cost = 66×25=1650 rupees
