THIS IS THE CONTINUATION........
area of the semicicle ABCO is
π r²/2=(22/7*7*7)/2
         =77 cm²
area of ΔABC=1/2 bh
                      =1/2*7*14
                      =49
∴area of shaded region = 77-49=28cm²
area of total shaded region=28+38.5
                                           =66.5cm²
hope this helps you........mark as brainliest pls and say thanks
