Side of pentagonal park = 30m
it's Perimeter = 30 * 5 m
                      =150 m
According to question,
Perimeter of Pentagon = Perimeter of rectangle
and breadth of rectangle given = 15 m.
∴2(l + b) = 150
   ( l + 15) =150/2
   l = 75 - 15
  ∴ l = 60

P of pentagon =30*5=150
p of pentagon=p of rectangle
2[15+b]=150
15+b=150/2
b=75-15
b=60m
