Answer:

The answer is "
44 \ m^2"

Explanation:


R=4.5 \ m \\\\r=2.5\ m\\\\

The area between two concentrated circles via an exterior circle radius R and an internal circle


r =\pi(R^2-r^2)

The region, therefore, consists of two concentrated circles with radii of 4.5 m and 2.5 m.


r=\pi(4.5^2 -2.5^2)\\\\


=(22)/(7) (20.25-6.25) \\\\ =(22)/(7) (14) \\\\=22 * 2 \\\\ =44 \ m^2
