circumference = 2πr

circumference of outer circle = 44m

44m = 2πR

44m = 2 x 22/7 x R

44m x 7/44 = R

radius of outer circle (R)= 7m

radius of inner circle (r) = R - width of path = 7 - 2 = 5m

area of path = area of outer circle - area of inner circle

                    = πR² - πr²

                    = 22/7 x 7² - 22/7 x 5²

                    = 154 - 78.6

                    = 75.4m²
