To find the area of a semi-circle, use this formula:



To find your answer, first get the two dimensions of the rectangle



and multiply.



Now look at the semi-circle. We can see that it has a diameter of 3. Since the radius is equal to half, 1/2 the diameter, our radius is then 1.5.



We can also calculate this manually:



Add the dimensions of both objects together now.



Your geometric figure has a total area of 24.5325 cm.
