The Solution:

Given:

We are required to find the area of the shaded part.

The formula for the area of the sector is:

$\begin{gathered} A=(\theta)/(360)*\pi r^2 \\ \\ Where \\ A=area=? \\ \theta=149^o \\ r=radius=12m \end{gathered}$

Substitute these values in the formula.

$A=(149)/(360)*\pi*12^2=187.2389\approx187.2ft^2$

Therefore, the correct answer is 187.2 square feet
