The image you uploaded shows an irregularly shaped figure divided into smaller, labeled sections. Each section has its own width (shown horizontally) and height (shown vertically). To calculate the total area of the irregular shape, you can sum the areas of each rectangular section.

The labeled sections are as follows:

1. First rectangle: Width = 1.5, Height = 2
2. Second rectangle: Width = 1.75, Height = 2
3. Third rectangle: Width = 1.75, Height = 3
4. Fourth rectangle: Width = 2.75, Height = 3

The area of a rectangle is calculated by multiplying the width by the height. Let's calculate the area of each section.

Calculations:

1. Area of first section = $1.5 \times 2 = 3$
2. Area of second section = $1.75 \times 2 = 3.5$
3. Area of third section = $1.75 \times 3 = 5.25$
4. Area of fourth section = $2.75 \times 3 = 8.25$

Now, sum all the areas to get the total area: $\text{Total Area} = 3 + 3.5 + 5.25 + 8.25 = 20 \, \text{square units}$

The total area of the irregular shape is 20 square units.
