Question
**Title: Calculating the Centroid of a Shaded Area**

**Problem Statement:**
Determine the x- and y-coordinates of the centroid of the shaded area.

**Given Dimensions:**
- \( a = 2.2b \)
- \( c = 1.9b \)
- \( d = 1.6b \)
- \( e = 1.5b \)
- \( f = 2b \)
- \( h = 2.7b \)

**Diagram Explanation:**
The diagram shows a shaded area composed of a rectangle with a semicircular cutout from the top left section, and a triangular cut on the right side. The dimensions are marked as follows:
- \( a \) is the vertical height from the base to the upper edge of the triangular cut.
- \( c \) is the horizontal breadth from the left vertical edge to the vertical aligning with the center of the circle.
- \( h \) is the total height from the base to the top.
- Diameter of the circular cut is twice \( b \).
- \( d, e, \) and \( f \) are horizontal distances along the base from the left edge towards the triangular cut.

**Solution:**
To find the centroid, integrate these known dimensions to calculate the center of mass of the shape considering the geometric distribution.

**Input for Calculations:**
- \( \bar{x} = \) [input box] \( b \)
- \( \bar{y} = \) [input box] \( b \)

This calculation will aid in understanding basic centroid concepts in irregular shapes, combining elementary geometric methods and algebraic representation.
