Answer 1

Answer:

Rs.1530

Step-by-step explanation:

Given,

Dimensions of given park=20m×15m

Width of flower bed =1m

from figure fG=BC-1m=15-1=14m

and EF=DC-1=20-1=19m

THEREFORE,

Area of flower bed=area of rectangle ABCD-area of rectangle EFGD

=AD×DC-EF×FG

=15×20-19×14

=300-266

=34m2

Rs.45 is the cost of manuring of 1 square meter of flower bed.

Therefore,

cost of manuring of =34square meter of flower bed
