Answer 2

Step-by-step explanation:

Let ABCD represent the field and the path is the shaded portion

the dimension of the inner rectangle EFGHcan

be calculate

EF=

EF=80-2x5=70m

EH=52-2x5=42m

Area of the path =Area of the ABCD -Area of the EFGH

=(80x52-70x42

=4160-2940

1220

cost of cementing =(1220x8.25)

=10065
