The area of the shaded region is 2,674.53 square meters.

Step-by-step explanation:

Step 1:

The circumference of a circle  = .

In the given question, the circumference of the inner circle is 122.46 meters. So we need to determine the radius of the inner circle.    

So the radius of the inner circle is 19.5 meters.

Step 2:

The radius of the outer circle = The radius of the inner circle + 15.6.

The radius of the outer circle  = 19.5 + 15.6 = 35.1.

So the radius of the outer circle is 35.1 meters.

Step 3:

To calculate the area of the shaded region we subtract the area of the inner circle from the area of the outer circle.

The area of the outer circle =

The area of the inner circle =  

Step 4:

The area of the shaded region = .

Rounding this off, we get the area of the shaded region is 2,674.53 square meters.
