perimeter of thepark along with wall is=2(l+b)=2(15.5+3.45)=37.9
Area of the park=15.5*3.45=53.475
Remaining area=53.475-15.5=37.975
cost of grassing=37.975*12.50=Rs478.68

Answer:
Here is ans
Step-by-step explanation:
L=? B=3.45m
L+B+B= 15.5 m
L= 15.5 + 6.90
L=8.60m
find area
Area = L × B
= 8.60 × 3.45
= 29.67 m
=Total expenditure = Area × Rate
= 29.67 × 12.50
= 370.875 ANS
