Answer:

113.04 ft²

Explanation:

The area of the ring can be found by multiplying its center-line length by its width.

__

The diameter of the circle that is the center-line of the ring is ...

16 ft + 2 ft = 18 ft . . . . center-line diameter

The length of the center-line is then ...

C = πd

C = 3.14(18 ft) = 56.52 ft

And the area of the ring is ...

A = LW = (56.52 ft)(2 ft) = 113.04 ft²

The shaded area is 113.04 square feet.
