Answer 2

Answer:

area of path=116m^2

cost of construction =8120

Step-by-step explanation:

side of square

A=30m

width=1m

side of inner park =30-1-1

=28 m^2

area of path= Ar(square)-Ar(inner side of path)

=A^2-a^2

= 30^2-28^2

=900-784

= 116m^2

cost of construction =70×116

=8120 rupees
