area of middle part + area of semicircle + area of semicircle
12×14- 12×7
12(14-7)= 72 m²
22÷7×7²=154
π3.5×3.5= 38.48
72+(154-38.48)=115.52+72
= 187.62

Explanation: In order to solve this, we must first find the area of the containing square and then remove the inscribed circle. Once this is done, we need to divide our result by 4 in order to get the one-forth that is the one shaded region. One side of the square will be equal to the circle's diameter (2r).
