Step-by-step explanation:
radius of ground = 175m
radius of ground-path=175-5=170m
area of ground=πr^2=22/7×175×175
area of ground-path=22/7×170×170
area of road=area of ground-area of ground-path
=22/7×175×175-22/7×170×170
taking π common
22/7(175×175-170×170)
=22/7×(30625-28900)
=22/7×1725=37950/7=5421.42 sq.m
