okay so say that the top rectangle is a 2cm x 8cm rectangle, the area is 16.
if the square is 5cm x 5cm, the area is 25.
the final rectangle is 9cm x 2cm, the area is 18.
for the semi circle, the radius is 2.5. plugging this into the formula 1/2(pi*r^2) would give you an area of 9.82
add these values together: 9.82 + 18 + 25 + 16 = 68.82
The area would be 68.82 cm ^2
