2pi(r+2)=44
=2x22/7(r+2)=44
44/7(r+2)=44
44/7r+88/7=44
44/7r=44-88/7
44/7r=308-88/7
44/7r=220/7
r=220/7 x 7/44
r= 5m
Inner circumference = 2pir
=2x22/7x5
=44/7x5
=31.4m^2
Area of path = outer area-inner area
=piR^2-pir^2
=22/7x(7)^2-22/7x(5)^2
=22/7x49-22/7x25
=22x7-550/7
=154-550/7
=1078-550/7
=528/7
=75.42m2
