okay,
what u do is find the radius of outer circle of which the circumference is given ie 2πr = 88cm which is equal to 14.01 cm.....
by using the radius subtract the radius by width given to u to find the inner radius of the circle ie 14.01 - 3.5 = 10.5cm. Now find the area of both the circles and subtract the areas to get the area of the path
